Recently the guild hit Supremus again -- or, I should say, Supremus hit us. You'd think this would be a fairly easy fight to master. Supremus has two phases: the first is a lot like Gruul except with no cave-ins, knockback, or Shatter, and during the second phase, he aggros random people and tries to reach them while moving at the approximate pace of a snail. Oh, and he sprouts volcanoes under other players that you have to avoid. These two phases alternate until he's a giant pile of rubble in Black Temple's scenic courtyard.
We can't do it.
The guild's been farming Black Temple for months and most of the usual roster is rocking at least 3 or 4 pieces of Tier 6 -- yet the vast majority of our Supremus fights end with more than half the raid taking a dirt nap. We've reached the point where even this is still usually a one-shot, but it's more than a little disturbing. How can you one-shot Illidan with 24 people still alive...and somehow fail to steamroll the giant McLootLoot?
To be fair, it's not just raids. I've seen players break out in a cold sweat over Talon King Ikiss on heroic Sethekk (which always confused me; the great secret of the fight consists of tanking him in the doorway). Others cite Grandmaster Vorpil, the event before the second boss in Blood Furnace when you don't have a Paladin tank, or Warbringer O'mrogg on heroic Shattered Halls (actually, all of Shattered Halls can pretty much bite me. I hate tanking that place). My own personal nemesis is Vexallus on heroic Magisters' Terrace. I've even taken a group with two mages and a rogue in T5/T6 here and wiped 3 times. What gives?
