Eye for an eye, and perk for a perk
Since the very fair reasoning behind the remo- wait, sorry, rework for ruin was "fun" let's address another perk that can receive the same threatment.
Dead hard. Why? Personally I find dead hard very frustrating to go against, and you know that moment, that moment when you are about to smack in the ass the survivor that abus-, wait, sorry again, made great use of some very fair loops, and gets either another run or escapes and gens are done in mean time. And I am not the only killers that finds this perk that fun to go against.
Speaking of how over powered is, it is not that big of a deal to be totally honnest, but it is totally UNFUN to go against, and since that seems to be a rational and good reason for something that is quite important to use, I suggest remo-, crap not again, reworking dead hard. Rework ideas? I don't know, something to make it equally as good and viable as HEX, saying it out loud, HEX, Ruin is. Maybe when you activate instead of dashing forward and have that immunity frame you could I don't know, do a mario type of leap but for a short distance in the air. Or make it so it is 1-time use/game. Or make it so you do a Michael Jackson type of spin. Something to be in line of how ruin is going.
