you only need something like 169 as fury because of precision giving you 3%. If thegreatme is alliance you can further reduce that number by another 32.9 because of draenei racial.
Out of idle curiosity, I looked up Thegreatme after watching his raid strategy videos. I noticed that he Had gemmed straight armor pen and looking at his gear, his hit rating totalled up to 139. I can see armor pen gemming being a good idea, but Isn't the hit rating too low?
Thegreatme is Alliance! So yeah, he only needs 4% hit rating.
