I dunno marksmen is pretty nuts right now.
Openning aimed shots + arcane + killshots could do some dmg.
Survival does alot of burst had has an extra cc, so you could have traps and sleeps going.
After the opener i have no idea how well the hunters would fair. 4 Hunters + a healer (non-boxed) probably a better comp if you were to get serious with multi-hunters.
