Why are low standards for dps acceptable?

[Archaell]

DPS get blamed for *everything*. I was in a Lv. 50 roulette (TTD HM) the other day where the healer was mad that our BLM wasn't using Lv. 60 abilities, going on about how bad his/her DPS was despite the fact that we were going at a pretty steady click.

It always surprises me when people have time to watch others. How can they focus on their job? I am usually too much busy throwing stones/holy novas, watching tank's hp, keeping track of CDs and avoiding aoes, while keeping the rest of the group alive.

Maybe if I was not dpsing there would some time... but that sounds boring and not effective.

Of course if things die at slow rate I might start questioning the cause, but that must be one seriously bad performance.
