If you're casual it won't matter much but outlaw is still king for now. assassination is great fun though.
After seeing them I can tell that:
-Outlaw was slightly nerfed, it's still probably going to be best spec,
-Sub and Assas got buff, much better than before,
The question is if Assa and Sub will be better than Outlaw, though I'm not seeing this.
the outlaw nerfs are so minimal as to be unnoticeable, sin buffs will just mean we beat them by 20% instead of 30%
Sub will be a god later as usual
