DPS is the job of DPS.

[Aster_E]

That’s just poor play; has nothing to do with a DPS-only mentality. And people that are pro-tanks dropping stance will still say that tanks that refuse to use their defensive cooldowns are as dumb as a box of rocks when they say:

“Why did I die?”
“Did you use a cooldown?”
“No.”
“Then that’s why.”

Or, my personal favorite that I've seen a lot of...

"Why did I die? You're a bad healer!"
"You didn't use cooldowns."
"Yes I did!"
"No, no you literally did not."
