The 'unwritten rule' for non-tank pulls in dungeons

[Drayce1]

I go into dungeon pugs as pld only for a reason. If I deem the healer, dps or both too weak for mass pulls, I only pull two groups at a time and can keep myself up with clemency. If dps pulls more however, I let him die, unless they aggro healer. If healer pulls more, Ill take it off after letting healer take a beating for a bit to watch him heal himself back to full a few times, so he learns his lesson.

Overall though, its player impatience or overconfidence which is the reason why if I feel like tanking random dungeons, I go as pally.

Lol and no, never been kicked for it yet. Most know full well by kicking me I can just reque, probably get same group, or get one with hopefully brighter players within a minute or less. That if they do anyway they can be waiting up to 10 mins for a new tank, in that amount of time, could have finished or near finished the dungeon. Most are at least smart enough to know that. So far anyway.
