I thought Stonevault drops mail hands/gloves armor, but i’ve ran it 31 times already. And in WoW head the drop chance is 14%.
I’m starting to think it actually doesn’t drop.
I need hand armor to complete my tier set.
I can’t include links in my post, so search Yamhan-TarrenMill in rio or wow armory to see how many runs of Stonevault I got.
Any other dungeons I can do for higher chance of gloves/hands.
You got another gloves in Arakara.
But I am not sure where you got the other 3 tier set slots in. But you could transform a pair of pants (assuming you already have) in the catalyst for example and get your 4 set. 4 set bonus is much larger than any stat imbalance you get, which can be corrected and accounted for with rings and neclaces.
TLDR: Run dungeons because you like to run dungeons. You should never target 1 specific peice of gear in 1 specific dungeon. What you should do is target a specific stat priority and perfect it throught the season with the random drops you get from running dungeons (all of them).
