I would put a Ch check in there somewhere if it made any sense at all
Suicide prompting. If successful charisma roll - enemy cuts his veins.
I totally agree with aForcefulThrust. I hope you realize that many people tend to play in TB and these anti-crit perks (however, not many will find "a place" to use them) + nerfing critical chances + ST for weapon drop (BGs tend to have high ST anyway) are good changes to BGs and really bad news to snipers.
Higher dmg is the only thing that SG can get and actually 150-200 isn't enough to kill a BG.
It is way easier to MAKE a two burst BG than 2 shot sniper. BG with two bursts easily OWNS 2 shot sniper. You should nerf BGs somehow if all these changes will be implemented. Idea to make them impossible to run seems rational to me.
Or, that's the idea I will force to an end - raise APs for using heavy weapons, so that there are no drug-free 2 bursts BGs. It would lead to a situation when a one shot burster meets sniper with one shot or 2 shot crippler (with f.e. 14mm pistol). Sounds ok, cuz sniper doesn't have one chance before BG smashes him with 90dmg x2, but actually his chances are raised.
Game would be more tactical, at the moment if a sniper resps in the middle near BG his first shot NEEDS to be a blind/KO one, otherwise - he's dead (crippling one arm is not a good choice really, cuz there is a lot of hybrids like 220%BG/150%SG). That sucks.
