My tier list (including the new killer)
Please note i am including the addons being applied to this as well like for example gen grabbing spirit. I know a some say billy is op but i dont think so im a survivor main, being many times at rank 1 and still vs powerful billy i find it easier to dough him with his chainsaw making more of an 1m killer because of it. The reason i put other killers like pig and legion at higher tier is because their powers help slow down the game some like legion a little bit others like pig a better. Ive faced the new killer and for me he doesnt seem that good his lunge is easier to doung for me it feels like a slow mo billy and it wont even down you, his portals arent that powerful and they are easier to get rid of than hags. For me and my friends he his mainly an 1m killer but he is still fun to play against.
Wraith for me is the weakest due to the power makes him invisible but no good enough and high ranks many survivors can easily see him and even with add ons he feel extremly weak like leatherface except leatherface can 1 shot down someone unlike wraith. As well they should make an add on like ultra rare that makes wraith completely invisible like spirits phasing which could buff him. I know he can be silent when coming out of the cloak but what good is that going to do if the survivor can see you and knows where you are at.
The reason i put both nurse and spirit at the same tier is due to add ons and perks. For me if they both have powerful perks and add ons i find them equal but for example without add ons i find nurse more op than spirit. Please as well note this is just my opinion, yours might be different. This is how i would rate from my own and my friends experiences. Please as well tell me what you would do different and why

Her power offers no chase time reduction, and the ambush is a joke, in most loops you have a clear vision of the killet and if she starts the ambush you can just open more time. Also, the traps are awful, they are luck based and addon dependant. So if the person you trap just gets off it in 40 seconds, you just lose.
Demogorgon should be in the S survivor tier. Because he just wants to give the survivors a kiss c:
Where's Legion?
Oh sorry, probably the worst tiers, but higher than clown
At least they're better than clown :3
