Rogues are all about DPS. You've heard my spiel about us being the only pure melee class, which makes DPS the only thing we bring to the table. SportsCenter can claim that Tim Tebow is a great quarterback, in spite of his shortcomings, because of his "intangible" benefits. Rogues don't have that luxury. If you parse poorly, then you get labeled as a bad rogue.
I was in the Raid Finder last week, and a warrior from another server tried calling me out for using Cloak of Shadows to stay in during Morchok's Black Blood phase. "Hey, that rogue didn't run out, that's not fair," he complained in raid chat. The last time I checked, all is fair in love, war, and the DPS meters.
However, there is one higher calling than DPS, and that is the success of your raid or party. Even though it's against our nature, we occasionally have to sacrifice some of our personal DPS in order to benefit the raid.
