Some sort of weapon and 400+hp.
All i've ever seen even suggested a melee needed in any epic. And hey. Completed reguarly with everyone.
Only casters get the 3rd degree about builds and dcs... From leaders who really should not be leading anything. And often have no clue whatsoever about playing a caster. (tell the ice sorc to throw a firewall HERE. lol)
Just avoid those groups. You'll be saving yourself alot of bs and drama.
