If you've been farming and selling Arctic Furs, I suppose you might be a bit bummed that your cash cow is going away, but for the most part I think most of us are pretty happy with it. For example, if you're like yours truly, you have a stack of 20 Frozen Orbs sitting in the bank just begging to be made into something useful if you could just skin more than 1 Arctic fur every couple months. Then again, at 60 total Borean Leathers before you can actually buy one, you'll still have to put in some overtime with the skinning knife.
Overall, though, this is one more nice little thing for professionals (and any tanks or physical DPS upgrading to tier 9 or tier 10 legs) to get excited about in Patch 3.3.
Patch 3.3 is the last major patch of Wrath of the Lich King. With the new Icecrown Citadel 5-man dungeons and 10/25-man raid arriving soon, patch 3.3 will deal the final blow to the Arthas. WoW.com's Guide to Patch 3.3 will keep you updated with all the latest patch news.
