I have some questions,
1) Why didn't you get Art of War up to 3/3 in first Talent, only 1/3. A free exorcism is always good.
2)Why don't we need the Divine Storm ability?
1) Since it only procs on autoattacks, and we get kited quite a bit in arenas, the idea is that it's not worth the talent points.
2) Divine Storm does very little damage. Also it breaks cc. The only use for it is to try to get rogues out of stealth, and we have Holy Wrath for that.
