Was just thinking about some awesome raid mistakes I've made as the other tank in our 25 man raid (I'm now a disc priest):
- I death gripped the Spark of Rhyolith on 25H to the entire raid instead of a fragment that had escaped our group. We wiped
- I, without permission, brezed (last rez) one of our lesser DPS during Alysrazor 25H. We died with 3% to go because that brez would have picked up our tank who could have held the boss just a little longer before she turned on everyone and smashed their faces
- I fell off of Deathwing a few times on Spine
What other fun things have you done, not necessarily on purpose, that have resulted in spectacular raid wipes?
