Freddy.

Still nothing to justify why this version of Freddy is "boring to face." What's more boring? Just falling asleep, or having to contend with dream snares/pallets and teleports as well?

I'm telling you, you undo the nerf, he still won't come close to being strong in the modern meta, because he wasn't even back then. That's just step 1. From there, you give him other buffs, like the very much needed qol change of being able to place snares, and not fidget around with it until it decides it can spawn somewhere.

The fact that he loses his power as the game progresses is a big issue. Completed gens remove teleport locations, and once the exits are powered he's just a basic M1 killer.

He could do with something that increases as gens are completed.

Maybe the sleep timer decreases by 10 seconds for each completed generator, so survivors end up falling asleep quicker. This would mean more survivors are asleep more as the game progresses, which reduces his cooldown.

Then maybe when all gens are completed he gets a 1% Haste for each survivor in the dreamworld.

That could be a good Iri add-on, teleporting to completed gens. Maybe instead of the Black Box. With the addition of something like I suggested before, that would be a valuable Iri.

Give Freddy a gun.

Freddy's dreamworld needs to do something because currently all it does is allow survivors to interact with your power and give you a minor cooldown decrease to the teleport. I'd say it needs to be more like Dredge's power but I already feel like Dredge is kind of a better freddy anyway? While this isn't the best idea out there but I've made suggestions before where when survivors are in the dreamworld, any other survivors more than 16m away from their position look like freddy, mimick his movements and even have the red stain along with a tiny, fake lullaby. It won't fool everyone but I feel like it gives a little more flavour and personality to his power and I think it'd fit him pretty well.

Personally, if I were put in charge of spinning out some ideas for how to address Freddy, I'd look at making him more interesting and fun before I look at trying to make him stronger. The way I would achieve that is twofold.

1: Make snares and pallets basekit, have him cycle through them like Clown swapping bottles. The pallets are by far the most interesting part of current Freddy, and you have to give up the more useful power to even use them when I genuinely believe there's no reason. It wouldn't be OP for him to have both pallets and snares, so just let him have both. Maybe up his ammo count a little so it can be shared between both.

2: Complete addon overhaul that chucks out basically everything he currently has, in favour of addons that give him more fake objects. Fake chests as the lower rarity, fake hex totems that flicker and crackle like the real thing, fake generators that appear partially repaired and just begging to be interacted with... these would function slightly differently to one another, in that I think just touching a fake generator causes it to disappear and you to scream, but fake totems let you actually finish them (without being affected by any buffs or debuffs to totem speed) before they disappear and you also, scream. Higher rarity versions of these addons could also inflict status effects and such. Basically, have the dream world be his to control, where survivors can't trust their eyes and ears because anything could be fake-- give them some pressure to want to wake up without just slapping a flat action speed penalty on them. More interesting for both parties, even if it may not be all that much stronger.

(As an aside, Freddy is a predator in both incarnations, it's just more subtextual in the originals. Or so I'm given to believe, I never watched the remake.)
