Stats haven't changed much.
Mastery > all by far for 5 man content;
in raid content depends on the fight, raid size and your legendaries/talent choices as to how often you're going to get return from mastery.
Haste > all in a vacuum for single spell hps but in reality pure volume of stats and int from ilvl will serve you well as long as aren't too vers heavy.
Vers scales strongly against all your other stats so the more of other stats(and pure ilvl) you have the stronger vers appears. Vers on a few items is good.
Mastery > Haste >= Crit > Vers with a heavy item level weighting works fine with germination in a smaller raid.
