I play a Shadow Priest.
Stat priorty is Intellect > Haste > Critical Strike > Mastery > Versatility.
So why on earth would a 187 item w/ Versatility+Mastery give a larger DPS return than a 216 item w/ Haste+Mastery?
The 187 Main Hand item would replace this [item equipped currently]:
…and likely pair with one of these [items I own currently]:
Whereas the Head item would replace this [item equipped currently]:
I use Ask Mr. Robot so that I don’t have to do the math, but this seems a little strange.
Looking for a reasonable explanation.
