Our simulations show Haste as a good stat for Outlaw. Checking some simulations with your character, it is possible to avoid wasting Energy even if you had twice as much haste as you have now. I don’t think that energy-capping due to haste is a big concern if you are able to play optimally.
The secondary stats are actually pretty close in value for outlaw, except mastery is a bit weak for multi-target. I don’t think you are going to see a noticeable difference between gearing for crit/haste/vers or any mix of those three stats. I’d go with what feels better to you in-game. Haste is just barely edging out the others in our data, so the optimizer tends to prefer it in many situations.
