Dude do you have a main, like not this rogue but a previous charecter?
Because its just so wrong to twink your main.
Sure you can have a great dps tree. but theres all these twinks with mains giving htem gold for hte best weapons, armor and enchants they can get at level 29. Not to mention they'll have better experience with the game overall.
Teamwork for example is very important. Specially for the most squishy melee dps like a rogue.
And please put in some details.
Are you horde or alliance, what race, where do you plan to pvp, your server type. The pvp battlegrounds you plan to fight in.
