Please bear in mind that stats can differ per player based on your stats and gear, make sure to sim yourself.
Single Target Stat Priority:
Critical Strike > Haste > Mastery > Versatility
Multi-Target Stat Priority:
Mastery > Haste > Critical Strike > Versatility
Mastery: Your mastery is called Master of Beasts, increasing the damage done by all the pets and creatures that you summon. This includes your main pet, Dire Beasts and more.
Critical Strike: Increasing your chance to critically hit with all spells and abilities. BM Hunters have another passive interaction with Crit called Wild Call if your auto-attack crits it has a 20% chance to rest the cooldown of Barbed Shot.
Versatility: Increasing all your damage and healing done, also decreases all damage taken.
