Rogue is not about damage as he is about utility. They also scale a lot better with gear as they are a melee class, so your weapons are a most importand factor of increeasing your damage. Go check Reckfull @ lvl 85 when every rogue had free daggers, and he was using glaives just to show off how high the skill cap of a rogue is once you know your shit.
In conclusion, get the honor gear including weapons, socket pvp power if you only do 2' and bgs and voila, you will instagib your opponents.
