2v2 Arena

Hey everyone.
So after many years spend on WotLk with warrios I wanted to try something new. I've made warlock :D I remember that back in wotlk wlocks were counters of warriors and other dps classes. My question is... What happened to them in Cata. I mean Iam full ruth+ off set cata, in battle grounds IF someone hold the dmg wlocks are unstoppable but 2v2 is really hard. And also I can notice that population of warlocks is rly low. Does Blizzard cut our (warlorck) "wings" or Im just low? (Im playing destruction/aff)
