After people started leaving, I jumped my THF to the main DD party and the results weren't bad. First run had me at 14%, drg 15%, mnks 16%/16%/18%/18%. Second run had me at 17.5%, mnks at 16%/17.8%/18%/18% and one pickup mnk at 10%; my damage picked up a bit because I wasn't sharing piercing weak with the drg anymore. Third run we wiped because being a DD, main curing and being the only stunner is a bad idea. Seems alt+tab'ing can only do so much. I don't run a bot, so people died, stun resisted and we wiped.
And also, the core members of my group are all top tier players, have mostly capped gear and everyone has mega boss weapons, and know how to play their job well, so I'm not parsing against a bunch of gimps.
