I have some suggestions for you:
- First off your belt clearly needs an upgrade ASAP but beyond that your gear looks pretty good.
- Gemming choices are mis-guided, you don't need that much hit as Fury so you DEFINITELY don't want to be gemming for it. You only need to be over 164 with Precision so replace all those gems with Str. Only utilize something besides 20Str for your meta to work, other then that you should be going all Str as a Fury warrior. Most socket bonuses really aren't worth going for, just use 20 Str.
- If you really want the speed boost you can keep your boot enchant but I prefer the AP enchant to maximize damage output
Most importantly however you need a good method for keeping track of !Slam procs. I use MSBT with both a text and sound notification of the Bloodsurge proc as well as Satrina's Buff Frames to give me a bar showing exactly how much time I have to use the instant slam. There are many options for how to keep track of it, just make sure you use something that is easy to see, preferably a sound notification and that you work on your rotation and never rage starve yourself.
Really we would need a WoL parse to get a better idea of what you could improve on.
