I am in the process of saving up 30k honor to buy one of the battlemaster's trinkets, but I'm unsure which is best for arena. I'm not sure if spec/gear makes a difference, but I will be 17/44 arcane/frost and I have mostly vengeful/veteran gear with 411 resilience. Anyway, I've pretty much discounted Battlemaster's Depravity since the advantage received by critical strikes is largely mitigated with the high resilience present in competitive teams. So basically that leaves me choosing between either Battlemaster's Audacity (spell dmg) or Battlemaster's Alacrity (spell haste). I have heard good arguments for both, but none that really convince me one way or the other, and I would like to be sure I am making the correct choice considering the cost of the trinket. Any advice from experienced PvP mages is appreciated.
