League levels of toxic behavour in game.

[Catwho]

As a tank primary for the last year, I also would firmly request that if a DPS pulls ahead, that they run back to the tank so I can pull aggro off. Yeah, it's only one or two buttons on my hotbar, but it's also a limited range, and I really get annoyed when I have to use a provoke or even my ranged attack to pluck mobs in content that shouldn't require it.

Side note: Tanks would feel more confident to pull if they weren't seeing their health drop to less than 20% with a grudging Regen being tossed their way, so the healer can fling a few more rocks.

Counterpoint: Most healers will let their tanks drop to 20% so they don't feel like they are wasting their big heal on someone who still has half health.
