You know, I was thinking the other day as a warrior was killing me from 100% to 0% during a Titan Strike stun that Rogues don't have a lot to offer in PvP that isn't done better by another class.
For single target damage, we are outpaced by warriors, and warriors have much greater survivability. For AOE damage, all the other classes outpace us completely. Warriors can even apply an incurable AOE healing debuff.
When it comes to healing, bards are light years behind chloro/lock or almost any healing-type cleric.
In fact, the only areas where rogue has an advantage are speed with the flag runner specs, and Eradicate, which is the best offensive dispel in the game.
Nightblade used to be an exception to this rule, but the other classes are so far outpacing NB damage now that it feels like your spitting into the wind.
Just some thoughts. Anyone have a PvP spec or style that doesn't feel like you're a massive underdog? Let me know!
