i think emmett has longest ranging shotgun now. i thought it would suck not being able to do big combo's but i am happy i can get a lot of AP regardless. being able to blast people away with majority of his attacks helps gives you time to setup your area.
Though his machine gun misses pretty much every small character in the game.
I also 1v1d with him yesterday against one of the people who can fight on par with me. His level 3 is actually reall good and I managed to get 3 kills with it. He dodged the bombing run at the end but he accidently jump into the mines trying to dodge it XD.
