The thing is no matter what you say, SL/ SL is the strongest spec inn turms of arena (As a Warlock) but its so slow and you cant always pick your battles. You kinda picked it at the first tick. Do your dots & run and land some good fears with a followup CC from your partner and keep going and you will most of the time win. Not always but, I like it more ruff and well you know like destruction! :D
