- The trash at the start of the Dread Approach wing of Heart of Fear in LFR. I think they put the normal mode trash (which barely moves a tank's health bars) in LFR by mistake and the LFR trash in normal - that's the only explanation for how overtuned it is. You're supposed to have one tank take the shield master and the other faces the packs away from the raid, but I've never seen another tank that had a clue about that. Trash isn't in the dungeon journal.
And c'mon, most of the healers are still eating and here comes the hardest-hitting trash in any LFR. Also, you constantly get evade bugs when you get to the platforms.
- Unskippable cinema sequence on Tortos. Yes, I would like to skip it, thank you. Do you speak English, button?
- Iron Qon resetting. He did this to us at 2% on the last phase the other day and I almost ragequit.
- Any boss that resets due to someone being locked out of the instance. Especially fun when someone ninja pulls while you're waiting to kick an AFK and gets killed. At least as the tank, I can, and do, put my foot down and wipe it if I know it's going to reset anyway.
