My 2v2 is hovering around 2100, with an Arms Warrior.
The thing is, vs. non-warlock teams, our win percentage is like 95%..... but vs. warlocks it plummets to like 30%
But from what I hear, rogues completely dominate warlocks, so I guess it balances out.
2v2 is way too rock/paper/scissors-y for my liking.
