Not gonna lie, as a tank sometimes I appreciate single target kills for extremely big pulls, even if not right away after a bit of AOE it still is helpful. I can only heavy mitigate for so long. After a few cooldowns if in large part all the mobs are still alive but low health, there has been a time or two I have died either from lack of large heals or i just didnt have any cooldowns left. Can't really blame the healer though with large pulls everyone is taking a risk. Realistically AOE is a time saver but at some point you have to switch to single targets to kill a few if its an extremely large pull and none of the mobs are dead yet after cooldowns are expiring.

The only time I kick from dungeons is if its an obvious script bot, lagging way to much to be of any use, or offline. Dungeons are so boring and faceroll but that doesn't entitle anyone to a speedrun unless they are playing with likeminded people. You go through roulette expecting a speedrun, you still gonna get what you get.
