Right I havn't really played on my Shammy since Naxx/Sath. Decided I want a melee class, I was previously elemental so I have NO enhance gear at all. I've been running the 3.3 instances hopeing for mail drops.
Is there anything in perticular I should look for?
badge gear will get u start, though most of it has ArP. Get your t9 pieces, then get off stuff. check WoWhead loot lists for the new dungeons and see what u can get before just buying non tier pieces.
A. Read the FAQ (conveniently Bolded now) to understand what caps you need to hit to ensure you are doing things correctly.
B. Use a tool such as WOWHead to create a filter for all gear related to the stats you need to find out where to get them.
Obviously you should be running heroics til your fingers fall off to pick up the full T9 set. Please don't expect someone to make a list for you as that is lazy on your part.
