triple box rogue

So i have been hearing some good info on the rogue and triple boxing that three is the magic key and with shadow step it could be some deadlyness for pvp. Some other mutliboxers in met on my server have told me that three rogues is the sweet spot when it comes to rogue and pvp


I have a couple of groups i am working on and i thinking of doing that orc dk team i just wonder how good the burst of frost plus a using the ghoul attacks will do for pvp with just three guys.


While i know my refer a friend thing will end soon so i should i make a triple box rogue for pvp?

or would i better off with my 2x shadow priest and restro shammy (dk just dindn't work out so well) or lvl the crap out of my rogues?
