It's possibly the best gun in the game, so there's no argument there, it's just that there are kits better suited to exploiting it. Among infiltrators, both the Ghost and the GI are going to get you better results.
I feel like the AIU is made for either the Claymore or the Reegar, with Wraith/Crusader/Piranha being the next tier of options.
Much more suited to the Claymore imo. the Reeger is a fantastic gun, possibly my favourite shotgun, but it takes too long to make the same damage as the Claymore. THe AIU is built to take that one BIG shot and then dive or get the hell out of there.
Even after the nerf, im always topping the leaderboard on Gold and she is the only character which makes me look decent on platinum.
