first off Thank you superbot for both Emmet and Kat. I main Emmet now and I love the way he plays, but I think he needs to be tweaked. First off his side square move, takes much too long to charge and has no range. Secondly his rocket launcher moves take gain a lot of AP. If ths was intended to balance out the character's moveset and make him a primarily long distance character, then you guys have succeeded, but I feel like I'm forced to focus on a few moves in his moveset because of this and the tweaking of a few moves might balance it all out.
The MAW launcher, in my opinion, exists to help against characters that outrange his shotgun such as Ratchet and Kratos. Also to help his camping game, similar to the AP generator.
If you're noticeably neglecting your square moves try using them in the air, it's much safer since they have no dangerous wind downs. Emmett is a very tricky character to fight at close range, most of his moves have no wind up to speak of.
