I'm building up my warrior tank and I'm not sure what else i need cause i'm close to 490 but not sure what i should replace or what i should keep and where i need to go to get better armor
Check out Polar's pre-Kara gear guide under the Gear List link on main page. As a fairly new 70 tank I found it very useful for finding non-instance gear
Replace the gems in your felsteel legs with all +12 stam, it seems you have the money, and the socket bonus isn't worth it. I'd say the same for the helm, AP is useless for prot warriors. Gloves too - you are sacrificing 24 stam for 10 stam 4 defense rating 3 parry rating and AP. Not worth it.
Get a leatherworking friend. Trade him jewels for heavy knothide armour kits and chuck them on every one of your items. It is an easy way to boost your hp several hundred.
Check my armory http://www.wowarmory.com/character-s...light&n=Kaetun and thott my rings, belt and cloak. All good for you. Get the clefthoof armour kit for your legs. 300hp extra not gonna hurt even a little. I recommend getting PvP shoulders, they blow away everything else out there in terms of armour and stam. Lack of avoidance stats is sad, but you are getting 17 parry at most from other pieces, the difference in armour stam and slots makes up for it many times over.
