Well for me, as a not pvp player(hush, dont insult me that im not playing that not balanced shit, sorry) I know for ANY player that heavy handed are "butthurt" and this is why : combined with ac, one can get to you, and endless kd you to death, and you lose precious gear, while when he dies, he loses only 1 minute of time, then gets back to the city, and so on.
I do not mean to just NERF all features we got in game, but balance it, ex: add it to the melee weapons also, and decrease the kd chance, so one got enough kd chance with sledge/power fist, super sledge/ mega fist.
First problem solved.
AC problem: It might sound shitty, but the true is, target is running almost always in fancy blue suit, just nerf that by adding disadvantages running in bs ( -100% sneak -50-100AC, you choice, because its colours are bright), and mess something with BGs and their miniguns, or add hex shooting for bazooka.
OR (another shitty idea) you can make when AC troll got hit but missed more than three times, he loses his bonus for 1 - 10 seconds, or loses all aps.
Those are just ideas, or my opinions, Im not against anything, but balance.
