Biggest pet peeves when it comes to dungeon runs?

[Nestama]

I meant I'm not sure if intentionally pulling more for a tank because they aren't pulling enough for someone is griefing or not.

Responding to such a move by not taking is griefing no questions asked.

Unless it leads to a wipe (due to tank and/or healer genuinely being unable to keep up), I wouldn't see it as griefing.

We're letting the DPS die for being foolish. If I'm the healer, I'm not healing you if you do it. If I'm the tank, I'm letting you die for it. If you wanted to control the flow of the dungeon, you should have come in on a tank.

And this right here is a toxic attitude that can be reported. Tanks DO NOT control the flow of the dungeon. The party overall does. DPS control how long you're in the dungeon (if they're good/fantastic, less time in dungeon. If they're bad/terrible... well, you know), tanks control the mobs around them and healers keep people alive (and DPS to assist in dungeon length). It's silly to say only the tank controls the flow.
