Thinking to try alliance

Hey guys, I was always a horde player and in classic through wotlk as well.

This time with the pvp balance, I am thinking to go in as alliance. my friend tho wants horde and playing a shaman.

Should I go as alliance or stay as horde with my friend :p.

I got tired of huts and looking at the same side, I want to kill hordes thinking dwarf priest.
