How about do the math. If Tanks start the game knowing that 3/4 of them are going to be sitting on the bench once they reach op level, there's less incentive to level as one. Then you get a horrible imbalance of DPS/Heals to tanks, and have a hell of a time doing FPs. As it is, I OT ops, and that largely consists of Ad duty, and dealing with a steady stream of 'what do we need you for' jokes, which are wearing thin. Fun times...\sarc

Cannot agree with the OP enough. I'm tanking flashpoints and ops on a regular basis, and I spend more time focusing on my taunt timers than my threat ones, because I know I'll need to keep taunting mobs back. Despite being specced heavily in the defensive tree, I feel like a DPS that has a few more survival buttons, rather than a tank that can reliable keep threat from pull to pull. Please reassess the numbers!
