I really haven't called for a nerfed on much in this game, my only issue is the damage difference between fusion grenades and Flux grenades. I just don't understand it, magnetic grenades explode twice, so I get them not killing on the initial burst for a full health character. That being said Flux grenade seems to be extraordinarily under powered, and have a lack of efficient tracking compared to fusion grenades. I'll say I really don't find it to affect my game play much if at all, but still is something I simply don't understand.
