this is assuming you have read and understand notes regarding the new dungeon finder.
if 3 people queue up with a tank and then the tank drops, those 3 people will be removed. however, the one lone person that just spent 42 minutes in queue waiting for that group is now sitting alone in the vortex pinnacle twiddling his thumbs wondering why he just wasted 42 minutes. lets punish the people that have friends that can queue them! and any1 without friends gets 1000x more screwed, altho we are trying to help them out.
