Help Prot Warrior.
I dont know if im supposed to stack for stamina or if im reforging correctly. Basically i dont know what im doing.
Some help would be appreciated.
Looks alright, what you want is getting 102,4% CTC (dodge+parry+block+miss) and stacking stamina after that. You're currently at 98% unbuffed which would be around 100% with buffs & food. So get a bit more mastery for the last 2,4% and then go for more stamina.
Easy upgrades would be the cloak, helm and shield from 5mans, vp neck/belt and some epic gems in the 397 you won't replace any time soon. I see that you've killed hc Morchok. Get the 4piece T13, doing hc modes without it is just gimping your raid, healers will love you for it
When you say "go for more stamina" do you mean gem up on stam?
Yeah just switch in some more stamina gems while keeping the CTC cap.
You could also grab the Firelands mastery trinket or Stay of Execution (reforged to mastery), either would come close to covering the last 2.4%.
