Personally I don’t have a super hard time spotting them. Their model is a lot thicker than pretty much every other humanoid model. Although I will agree the lack of colors can make it hard to see in crowded groups.
Maybe he could have some bright gas coming off of him.in small amounts? No gameplay effect, just a visual hint.
While I felt this was when it launched, I’ve been hearing him more and louder. He really, really likes talking about Nurgle.
I will say, this is my biggest problem with the enemy. It just feels very annoying to deal with imo, and has quickly become specialist priority number 1 because of this. Personally the biggest change I would like to see in this department is just have the gas spread slower out from his grenade he throws. This would give a more time to reposition, so there’s a a bit more counterplay, while still achieving his goal of area denial and enemy buffs.
It does, here is what FS said about. Additionally it makes Mutants run significantly faster. I don’t know if it has any other specific buffs to other enemy types.
