I see this as killing several birds with one stone.
NT's aren't even close to proficient pistol users, and there's nothing else we could plausibly use in the left hand. However, we could use a little boost in the AR department. But then, we've never had any offensive procs. Per the nano documents, we were supposed to get damage type override buffs, and our description is consistent with that but misleading currently.
Multiple entries or not, it's a pretty inclusive fix to several outstanding issues. And, there are plenty of crappy items in this game that could be deleted to make room for something new and useful
