Well its defficult when you dont say what rotations you use and stuff like that.
However, your gear seems fine except one thing, you have WAY to much expertise, try to drop it down to 18. Another thing, when gemming its not always worth going for the socket bonusses, mostly thinking about your neck here, as a warrior you wont need extra stam since we allready have plety from our gear, and a 6AP bonus is simply not worth it, change it to 16str instead.
As for rotation, start by aplying rend, and after that the following priority list is the best: MS>exe>OP>slam, reaply rend once it falls off.
hope it helps.
