I've played against you before, got stomped every time so I suppose you shouldn't take my suggestions with too much seriousness.
Honeybadger already covered the armor but I disagree with a few of your enchants.
As you mentioned earlier this does depend on each person's playstyle.
I would suggest changing the pvp power back to
Enchant Cloak - Superior Intellect aswell as dropping the mana enchant and getting
Heavy Borean Armor Kit
I feel as if the pvp power isn't helping very much and the mana is wasted, I personally never go oom but then again, I'm not you
If you disagree with me in any way feel free to talk to me about it, I'd like to know why.
