What do you think if in game would be the possibility to lose hands for Fireteam? They always want to parry you and would be nice, if they missed or made something wrong they lose their hands and gets bleed. (i think it fair considering how much parry is absurd and OP, just a little price for a mistake, but if you make all right you get no damage) Also, a direct shot of full charged plasma to hand would be cut it off (how many times you directly hit an enemy with full charged plasma, so i think it will not be OP or annoying). And maybe melee attack in hand hit-box could have a chance to cut it.
Without hand you bleed, you can run away and your team could heal you or you could heal by yourself (in solo) if you have a special medkit. Without hand you can not use a heavy weapon, you still can shoot with one hand, but with less accuracy and you can not reloading and use equipment in moving, new reloading animation with one hand is required, also your teammate can reload your weapon by PRESS F TO RELOAD TEAMMATE WEAPON. it is also necessary to think about the reward for winning \ surviving being without a hand
