i really hate ppl who says "its fine leave it as it is" its not fine... i was persistent to get it done but noone wants to fight the dragon so i was never able to do it... have only tried the dragon one time out of maybe 15 runs (then i out lvled the dungeon) when something is so though that 15 pugs out of 16 skips it it…
thats my experience... was doing the storm the keep skirmish with a lvl 28 GF and i was lvl 26 CW and i knew that GF had trouble holding aggro so on the final boss i only uses MM for the first 1/4 of the bosses health before i startet nukeing... and before he hit 50% health i had aggro...
