Fair enough, I think it depends on what you’re trying to do. My advice was more based around survivability over damage output. Mastery has been good for that. Icy veins for prot PvP also suggests going with mastery ring enchants and gems that’s where I based my initial secondary stat focus on.
For myself, playing as a tank in PvP, I’m not looking for damage output really, I’m more focused on surviving for objectives, support and disruption playstyles. If you’re looking to do some decent damage maybe haste and crit is the way to go!
It really depends on what you wanna do in PvP, my mindset is if I wanted to do damage I’d be playing Arms or Fury haha.
