4th job Single Target DPS

Well any class can kill any boss now solo/party anything. Its not a problem. Maybe not pb if you don't practice it. Just that ppl now try to take the least amount of ppl they can having the most dps possible to increase the split profit for each person and doing as much dps as possible. In that case there is high competition for those few spots. Best class + best funded gear is what we really need. Like the other classes except hero and maybe dk seem pretty well balanced i guess. However that hero's dps is a bit too high so everyone will prefer taking heros over other classes.

Fair enough; but in the extreme upper end (say, 800k+ per attack after accounting for def, cause that's when the cap becomes a problem) you're talking about a character that deals at least 70-80mil dpm on their own. There's not a lot that can stand up to that onslaught from a party - you could form your own boss runs if the heroes don't take you.
