Trapsins can deal with it alright. Though Hit and Run has been my most common tactic against Boss Packs and Champions with my lvl 72 Trapsin using FB and LS, currently working her way through Act 2 Hell, she can certainly stand her ground against any normal pack of monsters in Players 6. Sometimes even Players 8, with assistance from her trusty HF merc of course :)
In my mind, my dreams are real. No one's concerned about the way I feel.
