Well for one I would say post the armory link, for two this should be in the Halp! section.
I can't view the armory, but here are the basics: 26/26 expertise, 5% hit (with 3/3 precision). Do not spam heroic strike. Only hit slam! when it procs. Get an audible alert for your slam! proc. Gem solid colors unless the socket bonus is 6 or more strength. Make sure your crit is around 40% unbuffed. Use the Relentless meta gem and 1 nightmare tear to activate it to free up gem slots.
I'll try to have a look at your armory later for more specific advice.
