I'm new to stuns and LTL but from what I have experienced with the stun weapons from both using them and seeing them used is I agree that the PIG needs a nerf but only due to the meta of sprinkling some damage on a Criminal then slamming them with a stun. I can never time my stun grenades enough to weigh in on that argument though.
My main concern with LTL is that I feel bad for the Criminals that do get arrested. They've either got to sit there and wait in such an embarrassing pose or get humiliatingly killed once arrested. I just want to level up Cop, but I've got to play this way to earn it, I try to be nice, but there just doesn't seem to be a nice way out of the stun-arrest-repeat cycle, at least for the Criminals, I can't go a match without someone getting angry over it.
I understand why the wait timer is long, to give the other Criminals a chance to save them, but while I don't have the stats I imagine that saves from arrests are probably quite rare.
What I'm trying to say is I'd like to give Criminals access to LTL, or something similar, maybe poison attacks? Instead of getting arrested the Enforcer writhes on the ground vomiting their eyes out their ears or something.
