If you're running Castigator which is best single target Crit/Haste>Mastery. Both Crit and Haste are highly valued, so try to get those stats on gear. If you're running AoE/Cleave spec, then Haste>Mastery>Crit.
For the record, I'm at 850 and have about 30% Crit, it varies though because I'm running the DMF trinket. I also about 18% Haste. Some of my pieces aren't optimal having some Versatility and I'll probably have some gear crafted to get more Crit.
