Keep in mind that while Haste > Crit > Mastery is what is currently simming for single target, the stat weights are very close for crit and mastery so any fight with cleave or aoe mastery will likely pull ahead of crit.
The current sim with crit>mastery and 2H is single target, the majority of fights/dungeons whatever you do will always be more than 1 target, so mastery>crit.

With the current gear, go full str unless the socket bonus is +120 str or more.
