1. Not everyone who plays Demo is a Demo main.
2. Not everyone plays the same, some people dont tunnel, some people do tunnel, etc, it happens with literally any Killer, this obviously applies to Demo which results in people tunneling.

Depends.

Id argue that Demo has one of the better chase abilities in the game, obviously nothing insane like Blight or Nurse but Demo has a good enough power to hold their own.

If you go for a lot of shreds (which means missing a lot), Survivors start to become conditioned to you using your power, which means you can bait it and/or force Survivors to play around your presences at all times which not too many Killers can do (or have limitations to doing it).

His mobility is... alright. The prospect of Survivors being able to destroy portals can be frustrating at times, especially if you are wanting to use BBQ to get right into a chase, but if they couldnt be destroyed addons like Lifeguard Whistle and Lichen would become problematic so I understand the balancing.

Demo is kind of like Xenokitty honestly, difference between the two is what you are willing to trade since both fill a specific niche. Want mobility? Choose Xeno. Want a chase power? Choose Demo.

Demo has his power right out the gate.

Nemo has to work for his power only for it to basically do what other Killers (including Demo) can do.

Only redeeming quality for Nemo is the zombies and even then they tend to be a bit subpar... but they are kinda funny.

Making the fullest of Demo's range and hitbox is probably the hardest part.

Once you understand the Shred timing with range you can get some nasty hits with his power, especially involving windows since Demo has an extendo grip with his hitboxes.

There are also "SkyDemo" places as well, like the hole with the pallet on The Game, throwing yourself onto map-geometry can help, learning how to do it is also kind of advance.

What separates a Demo main from other Demos is how they view Demo's power.

Picture this, ahead of you lies two paths.

One is the STBFL user. They only M1. They never use Demo's power unless it is to hit the Obsession. They turn their brain off and dont understand Demo's power.

One is the Black Heart user. They constantly go for M2s and get rewarded for using Demo's power effectively.

Demo mains typically lean a bit more towards the Black Heart crowd.

They ated all the Rat Livers.

I think you can check the replies and get my stance... Im anti-STBFL.

It hinders people's ability to play by trapping them into never using Demo's power, and in my opinion if people play Demo without using his power they might as well just play a different Killer at that point bc Demo is clearly not for them (may come off as harsh, but I feel as if it is the truth).

I normally place 3-4 Portals at the start to get a decent spread, Ill use the other 2 on the Exit Gates later on in the match if I feel like it.

Rotten Pumpkin is a good choice for portals if you dont want to rely on Survivors cleansing Portals so you can replace them.

Still in the game but it is harder to pull off.

Also has unintended side effects like making the Killer stuck on a completely black screen or making the Survivors unable to move so I would not recommend doing it, it's the main reason why you never see people do it.

I feel like the comment Ill link below explains how I feel:

(I dont know anything about the show, Im really sorry. I want to watch it but Im too broke for Netflix atm.)

Launching myself from a Hill through Shack window and hitting a Survivor in Shack.

Literally nothing will be able to top that.

Pallet Stun => Aura Reading.

It's nothing insane but it energizes with Enduring and makes looping feel a bit better since you can mindgame pallets easier.
