I would suggest adding kills without any special features, which are activated after the death of the roles being killed.
And the Maniac definitely only has one normal kill, and it's much harder for him to rely on the fact that two teams will kill each other (and not touch him) without outside help.
I perfectly understand the desire to create a game where you have to think very carefully, and not just shoot, I just think it's important to point out the fact that sometimes, due to chance, everything ended very stupidly and without much thought.
And the Maniac has a kill after a block and the block itself; if he wants, he can kill independently - it just reduces his potential. I think that a simple kill for Windows 2000 would suit the concept, although you might be right.
