Right on, just what I've been thinking.
For prot how should I gem? I sit at 30k health unbuffed, ~44% dodge + parry, 541 defense. My hit is only at about 120 and my expertise is only at 17. I've been going for as much Stam as possible, socketing Expertise or Dodge + Stamina purple gems into Red sockets, and going for Defense/Stam in Yellow ones. I also use the 2% armor meta.
I was specced prot when I created this thread but had to go Fury for the raid, can anybody help me with protection gemming though?
you are still Fury when I just looked but I'll throw out some advice. 30K unbuffed is nice. 44% is pretty nice, youe expertise and hit are pretty low. Try not to lose too much avoidance, and try not to drop under 29K if you can help it, but i think you can add some expertise and maybe a little hit to get some more threat.
