DPS is the job of DPS.

Perhaps I didn't fully word it correctly but. Vast majority of the time I run into superman tanks they don't feel the need to use CDs. gotta increase that dps all the way.

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.”
