Resto shaman help

Hi guys! One quick question …

I main enhancement all the season, but now I’m switching to resto to help pushing m+ my friends (not so high mainly 12 13 keys). I’m 636, but with haste mastery equip (from enh) … is there a specific build for resto to take advantage of that stats?
Cause in every guide says crit versa> haste mast. But change all equipment will take me a while.

nope you need critic and versa and around 12 haste
