WW monk mythic plus gearing question

Is haste/mastery better than haste/vers? i see a lot of high ranked m+ scores with more mastery than versatility.

Once you hit a certain key level, you start to need to get more Vers so that you can survive the damage enemies do. If you’re not playing at a level where that is necessary then Mastery and Haste will be worth more damage in 11.1
