Trolls and jerks using Roll for Items as a shield.

[Mavrias]

This is the most annoying thing I've encountered as a white mage....next time I'll just stand there waiting...watch the tank get pissy...I'll just say - then why you run off? :P

Probably because theres auto run and right click > follow while you're rolling for loot and the dps have buff timers to keep up. If you need a minute, say something instead of expecting your tank to read your mind. Otherwise, we have a momentum to keep up.
