I played hardcore for a few years which is the online multiplayer but you only get one life and the servers are segreated so you cant benefit (get l337 drops passed on to you) from non hardcore characters. I normally played a sorc or amazon. The most fun character was a tank amazon, youd play with a jav and shield and max out your evade and dodge or whatever the skills were. So youd just run in there and melee with the bosses while your character dodges every hit and your party can sit back and crush them.
