Hey guys quick question, I already have a level 70 shaman.

Here is my question: would it be worth it to level another shaman up to dual-box pvp with? What I mean by "worth" would be of course 2 shaman wont have near the power of 5, but my capabilities only allow me to dual box.

So would two shaman be able to pack enough punch to warrant leveling up another shaman to 70?

Thanks
