Anyway, the first boss we got down to 20% before Alliance wiping.
Second boss was kinda miserable to be a healer since nobody figured out that chains mechanic, but no wipe.
Third boss (the one with the math mechanic), really showed who wasn't paying attention. Or didn't get the math. I felt this was a cool mechanic, but probably should have been more literal. Alliance wipe at 25%, one time.
Fourth boss, someone had the nerve to try vote abandon, twice. The co-healer from my party and two DPS from alliance A dropped out at this point (90 minute mark.) Unfortunately the new co-healer couldn't stay alive more than 5 seconds every time they were raised, so I tried raising the RDM instead, and that was not any more successful. (point of reference I had 38K hp, first co-healer had 42K. Second co healer had 36K.)
