M1 killers should be buffed
Killers like Ghost Face, Pig, Myers and I don't know if anyone else should get some kind of buff. A player with a minimal looping concept can easily loop on just vaults or even unsafe pallets, as those killers have no other way of hitting survivors but hitting them with an M1. Killers like Freddy or Clown at least have a slow, Demodog has his Shred, Pyramid Head his ranged attack that goes through anything, etc.
Literally if you face someone with enough hours, he will loop you throughout the game, without using all the pallets.
I don't know exactly what buff should be done to them, maybe Bloodlust activates sooner, or just rework their power, but something has to be done, because M1 killers, unless you face monkeys, are incredibly weak killers vs "press W" survivors.
