Okay, here's the deal.
A few weeks back, no more than 3 weeks, I bought my tier 8 robe (Conqueror's Kirin Tor Tunic - Item - World of Warcraft) for 58 emblems, which is a lot to me. I don't get to do many heroics or instances for that matter, as my playtime is somewhat limited. Then today in Pit of Saron heroic Ancient Polar Bear Hide - Item - World of Warcraft drops. I almost instantly needs on it, even though I just bought the tier one.
So, which should I wear?
I am well over the hitcap without the hide, and I'm trying to free up some hit rating. I need 289 hitrating as I am an Arcane Mage with both hit talents and I got 377 hit rating as it is. With the hide i'd be up about 438 hit rating which essencially would be good if I wanted to respec to Frostfire spec.
Currently I'm working on a mainhand/offhand combo instead of the staff I have now, to lower my hit rating a bit, also working on a new trinket, again to lower the hitrating. Also changing my gloves enchant first thing when I get the mats for it.
Here's the armory: The World of Warcraft Armory
PS: I'm ofcourse keeping my hitrating gear, if I decide to go Frostfire or Fire at some point.
