Luckily enough, I was able to snag my t4 helm last night off of Prince. It'll be the first part of my set, which I'm excited about, and gives me my second epic from Kara, next to the Shadow-Cloak of Dalaran. Here's a link for the helm and other pieces: http://www.wowwiki.com/Cyclone_Armor
Two questions reguarding the "socketability" (new words, ftw):
1. Being Elemental, any suggestions for 1 yellow and 1 meta socket?
2. How much do you think it'll cost?
