I agree with the first part because even at hard difficulty your passives/ skills overtake the growth curve by day 2-3 and it get's way too easy.
As for giving up, it's already in there, but to unlock it you are not allowed to pick the first edict and run away from fights at least 10 times.
however it only works if you're down... which again get's annoyingly easy with the passive accumulation for body parts.
Enemies, even on round 1 can force you down and get busy no matter how healthy you are. this should be looked at first and foremost.
Yeah I get that this is a corruption based game, but getting forced to do a foot job EVERY round when the first sector is rioting get's annoying very fast.
