Idk what game are those ppl playing, Warlock and Mages are almost non existant in arena nowdays, since 90% of the teams are KFC, and this guy wants to put them both, TOGETHER!
Let me just say that if my KFC team ever faces a team with this comp i bet we can kill the warlock before he has time to get out of his mount.
To the OP, the only chance you got is playing with a warrior that can peel for you, afflic can put out some nice pressure with a warrior burst you can score kills, but just be prepared to be tunneled by every other class and being useless against any team that happens to have a shaman.
