Demonology stat on gear

Can anyone explain to me why 99% of the TWW gear is stacked with versatility? I’m nearly at I610 with only 28% mastery…

Well it’s a good thing Demo likes all the stats and mastery is typically on the lower end of dps per point. But besides that, you’re just getting unlucky. There’s plenty of mastery gear out there.

Versatility is the bland filler stat Blizzard uses on gear.
It’s better than nothing, but not anything to get excited about.
