No perfect build and no ways to know well yet...
I know the wizards are stronger then nukers but die much easier cause of garment and pots less;
Warriors tank all the way over, the attacks are stronger than ever but no hp pots for a while makes them powerless for long battles;
Rogues, only if you know it really well it can be the most balanced char because keeping the enemies far or strongly hit them may be enough fast for auto pots to keep up, still for party killing then aren't much efficient for what i saw...
Warlocks, party?-> excellent! | pvp?-> hmm not so good;
Bards and clerics are fun to use, greatly thankful to exist, but for pvp...
Well my data may not be very correct but at least i tried
