shadow priest mastery

[Mako Mori]

Is it working in panda wow? When mastery procs and dots deal twice their damage, there's a double chance to proc From Darkness, Comes Light and Divine Insight I can't tell if my dots can deal double damage but I used to see higher procs from those 2 talents I've just mentioned. That's changed, I've seen fewer procs now, don't know what's changed. I've been thinking maybe latest server restarts have something to do with this but I can't say anything for sure. I'd just like to know from a trustworthy person whether or not spriest mastery is bugged.

Doesn't seem bugged to me. However, it's a mistake to stack mastery instead of haste on a SP.

Get pure haste, you won't notice less procs but more and you'll do a ton more damage, plus more mobility due to faster casting.

I'm not stacking mastery(even though arcane reforger won't let me reforge some gear pieces) What I'm asking is if someone's noticed any change. I used to get procs of both talents more often when I was wearing ilvl 408 greens than now that I have better gear and more haste.
