Spec is shitty indeed. First of all level 525 for alchi trinket porcelain crab always procs at wrong time. Farm wrathful chest for 4 set bonus, farm more honor for wrathful boots and belt or do lots of quests for cata ones and repleace ur haste ring with better ring from cata dungeon.
Stats what you should aim is 20 expertise, 5% hit ofc. I think you should reforge all other useless stats to mastery maybe some crit too because mastery is awesome.
I did chardev for you
