Playing as DPS can be stressful at times. Mobs don't die fast dps's fault, adds bum rushing healer dps's fault, oh Jesus I've ran out festers on the add phase of TT HM and we often get blamed for pulling even if it's the tank being useless and doesn't know what flash is (I pulled using bane once ><).

But I do agree as I'm playing healer now that it's equally stressful and I've played tank too on an alt to 30 and that's also stressful.

But unfortunately theres nothing we can do about stupid people.
