Giving the Assassin a go. Not sure what skills i'd want to give him. None of his particular skill trees seem like they'd be a lot better than the others.
The left and middle tree (sniping and invisibility) ones are the best. Not a fan of the far right tree, mostly melee stuff and melee is just not a major factor in this game. Sucks for bosses too.
Just grab a sniper rifle and headshot everyone. One shot one kill everyone with a sufficient sniper rifle.
