Hello. I wanted to ask you a pvp question for 2vs2 arenas.

Me and a friend are going to start playing in warmane to do pvp, I would like to play as a frost mage and my friend as a druid, but we do not know which branch of druid would be better (feral, balance, or healer).

As a last question, how about elemental shaman + druid? Which would be better in the end, a frost mage or an elemental shaman?

I hope you can help me with this question.
