Stealth rewards/ M.o.M change/ killer aura perk nerfs.
Alright, I play a fair amount of both killer and survivor. But I think the survivors need some more incentive to play more stealthy instead of balls out. Sure you can hide from the killer but only receive somewhat of under 100 blood-points. (Depending on how long you're in the killer's terror radius) Maybe increase the blood-points from how long you're in the terror radius to a default value.
As for the Mettel of Man changes, I think it's slightly over-tuned. I think instead of just taking hits or with the up coming protection hits. Maybe you should be awarded a stack if you can lose the killer in a chase after being injured. I think that could personally work well and still be fair to both sides.
Now for the killer perk nerfs. (this also ties into stealth) I think maybe reduce the range of aura perks. Like BBQ, Nurses, Bitter murmur. ETC ETC. Survivors can't play stealthy against aura reading perks. With the killer constantly being shown where they are or general location. It leaves the survivors to just running loops and some mind-gaming.
(Personal note: I'm under the impression the devs majority play killer a lot of the time and don't give the survivors the buffs they need.)
