Trying to find a killer that’s easy to use for a new player

Probably Wraith

I'm gonna assume you are just starting and have only the base-kit killers.

For me the best choice would be Wraith, you can start with a stealthier killer to begin to learn the usual places where to find survivors at the start of the match. It's easier to watch and learn from some of the things they do while being undetected. Also, you'll have a ton of speed so you can work on your gen patrol.

EDIT: But don't hesitate to give the others a try too. You never know, maybe you find another one that fits your playstyle better. Let me say if you feel comfortable with Nurse you will have an amazing start to this game lol

Assuming you have only base game I suggest wraith. He has predator invisibility and is truly invisible 20+ meters away. Has shadowborn to widen your fov, bloodhound to see blood easier and predator to see scratch marks a bit longer to help you track survivors.

DOCTOR, PLAY DOCTOR, in seriousness though, he is quite easy to pick up, use ability, survivor screams, walk towards scream, simple but effective

Let's not forget, bloodhound and predator are pretty meh perks, but i guess for beginners not terrible

Wraith and Legion are great options.

Someone with good tracking, and preferably generally a "M1 killer" that has to catch up to someone to hit them as it's important to learn the fundementals of how chases work in their most basic form.

Basegame only I'd go for Wraith. Perhaps not direct tracking, but you'll probably be able to start chases closer to survivors, catch people trying to hide from you while you're cloaked and he does also have some utility during chases with his uncloak that can be practiced. And while cloaked you move faster around the map as well, cutting down on travel time.

With DLC I'd recommend Doctor, as he might be the best at finding survivors out of any killer in the game. Newer survivors hide a lot, and often in odd places too. A quick static blast reveals them, which lets you get into a chase. His power also provides some anti-loop chase utility that does have a bit of a learning curve to use effectively, which is fun. Pretty interesting add-on design too, which lets you both directly improve parts of his kit, or add entirely new functions to it.

My #1 tip has less to do with what killer you pick, and more to do with your mindset: spend as much time as possible in situations where you can improve important skills, and a lot of the game boils down to chases so do a lot of chasing. This is why I recommend killers with good tracking and/or chase starting, as you'll both find survivors you can chase easier and pick up a thing or two about where people run/hide to avoid you if you pay attention.

You will get memed on by matchmaking and go against good survivors that give you trouble. It can be annoying but try your best to simply pay attention to how they play and what they do (If you haven't played survivor, I'd also recommend doing that - seeing the game from their perspective is quite useful in improving at killer, and the other way around too for new survivor players). While you're learning, do yourself a favor and try to not focus too hard on the end result of matches, if you come out of a match having discovered a better way to run a specific tile/structure or something, good job.

An alternative approach that is perfectly fine is to get Leatherface. He gives you BBQ&Chili perk which both gives you some information/tracking and the oh-so delicious bonus bloodpoints, and Bamboozle is also a good perk that blocks vault spots you vault for a while (even though I'd be careful, unless you plan to run it 24/7 it's important to learn how to deal with vault tiles without it too). He's also a perfectly fine killer to start with too, you still have to chase fairly "normally" but he has a power you can do some surprisingly deadly things in chase with if you practice it.

I second this.

You should do the Tutorial to unlock Wraith. If I remember correclty, he is locked behind the Tutorial as a Reward.

I would also invest some bucks into the Texas Chainsaw Massacre-DLC, this will give you Leatherface. He has a Perk (BBQ&Chili) which gives you extra Bloodpoints and shows you the Location of Survivors far away from you when you hook someone. This Perk helps a lot when it comes to levelling up characters.

But from the Base Game, I think Wraith is the first choice. He is easy to use and still decent, you wont have the strongest Killer, but he is not weak at all. Trapper is also quite good at the start, at least the basics are easy to learn, since it is just walking around, picking up Traps and placing down Traps, however, he has some learning curve, since you learn over time which Traps are good and which Traps only sound good, but are not good.

Stay away from Huntress and Nurse for now. Both are different from the standard Killer-gameplay, especially Nurse does not help you at all when trying to learn Killer.

wraith, pig, trapper even legion or ghostface any primarily m1 killer is very good for learning to end chases quickly

Also, one thing to understand is that you don't have to play a certain killer in order to level them up and unlock their perks. In the long run you should probably play all killers available to you at least to a modicum extent, just to learn what powers they bring to the table and how to counter them if you were to vers them as survivor, but if you just want a certain perk unlocked, you can play your favorite killer with BBQ and just pour that bloodpoints into whomever needs it.

That being said, we also have the Killer pack now, which gives you nearly all the OC from BHVR at a good discount. You will miss out on the survivors and some cosmetics from the DLC, but this is really an excellent buy if you know that you wanna stick with this game for a couple hundred hours; the package will give you a wide variation of different playstyles, nearly all of the meta or fun perks and you can change it up every so often, if you wanna try something new. Like I would never have bought Clown just for Bamboozle and he didn't sound that interesting, but he was in the package and turned out to be one of my favorite killers.

From the licenced characters (besides Leatherface, who is nearly a necessity because of the grind and BBQ) Nemesis is pretty easy to pick up as a new player, as he has a rather easy to use ranged power and a good way to get rid of pallets. His Lethal Pursuer perk also lets you see the spawn points of the survivors, which at the very least is a great learning tool and even a lot of high level players still use the perk for the early game pressure it generates.

Re: OP's question:

• Doctor: the power is very straight forward, it helps you find survivors and get into chases, and (at low levels) the madness can slow down generator progress. He has several very good Addons and has great use with a bunch of the default perks. Note: his front-arc shock has terrible validation, and survivors often get to throw the pallet despite having been shocked.
• Freddy: his power help slow down loops and gives you map awareness. Being able to teleport also speeds up your chase potential and combos well with some perks. He was nerfed in the most asinine way possible, so he's appreciable less good and less fun to play, but his core kit is still relatively accessible.
• Leatherface: His power is both very strong and does not require too much additional practice to understand (unlike Hillbilly's nearly uncontrollable dash + overheat mechanic). All you really need to learn is counting down when you have to hit the power to extend your chainsawing and how to avoid running into obstacles.
• Clown: His power is useful and does not require the kind of accuracy that Huntress demands. His antidote bottles are an added layer of complexity that you can safely ignore - a 'buff' that basically did not solve his core weaknesses. That being said, he's not all that good. You can get decent play from him at lower MMR, but will quickly be blown out of the water if you win too much. Still, he's easy to use.
• And that's pretty much it. Every other killer either has layers of self-nerfs (pyramid head, legion), requires extensive practice to learn their power inside and out (spirit, oni), or has a totally different skill system that is extremely punishing to even attempt to use without already being a pro (nurse, blight)

It's also worth noting that Killers that are easy to use and do not require a lot of experience to use their powers inevitably get nerfed (Freddy, Wraith). Killers that are very hard to use and take a lot of practice to learn their powers typically do not get nerfed (blight, hag). Though, this is not always the case, as we saw with Bubba staying consistent (though he was awful original and got buffed to his current state), or Deathslinger (who required a whole special skill set to use his hooking usefully and got a tremendous nerf out of nowhere recently).
