Rinnhart's got some great points. I can't say much about aggro control from a priest's point of view, but I can say plenty as a main tank.
In a party, in an instance, one of the BEST roles a rogue can fill, other than doing damage with the limitations discussed above, is crowd control. If you find sap and stuns to be boring, then you'll have to go zerg or raid the instance, and not 5-man it.
My mace/shield tank isn't going to out-DPS you, either, even if you hold back. On the other hand, you're going to have to crit a couple times in a row to pull a mob off her, too. Are your tanks in defensive stance? Or are they battle/berserk with a two-hander? HUGE difference in aggro generation by the tank in that case. If I stay in battle stance, it's trivial to pull a mob off my warrior. If I'm in defensive, and I have a taunt, a sunder, and maybe something else, be it rend/disarm/revenge, they're pretty much mine until they die, unless someone really nukes/crits badly, and usually if they hit that hard, the mob's dead or near death.
Stuns and saps are excellent team-helpers. If you don't wish to use that part of a rogue's arsenal in an instance, because it's 'boring', then you need to skip instances, or find another class. That's like my warrior standing back and just using her gun because she doesn't want to melee.
In an instance with my tank, usually the rogues I work with are firmly planted *behind* the mob(s) I have locked on me, beating the living bejeezus out of them. I have a slow one-hander, so it's like dagger-dagger-dagger-dagger-dagger-my mace swings for cleave-dagger-dagger-an instant ability for me-dagger. I mean, he's *working hard* up there, and doesn't sound like he's holding back any! In the very rare instance that a mob turns away from me to look at him, that's just before it falls over dead.
On the mage-vs-rogue question: I'll take a rogue who knows crowd-control over a so-so mage any day of the week. I've seen lots of mages who don't know how to sheep the right things. For a while, I partied with a 14-year-old who really knew his crowd-control as a rogue. Unfortunately, those rogues are as rare as the mages who truly know their stuff.
