You need 164 hit and 26 expertise and i would aim for arp softcap with the trinket from FoS and go for the arp hardcap once you get deathbringer's will. Any hit above 164 is basicly wasted since there is a heroic strike bug that will make your offhand hit if its que'd.
Now your warrior is kind of a mess 500+ hit is very bad. Lets get some easy upgrades first.
- Second trinket you want the one from FoS hc or if that doesnt drop the arp trinket from toc5 normal
- You dont need the hit so even the agi/arp ring from triumph emblems would be better
- Crafted boots are a nice upgrade, but since you lack expertise the ones from gunship icc10 would be even better.
- leather belt from frost emblems or expertise one from toc25
- axe from saurfang10 to boost your expertise
After that you want to aim for 4piece T10 with the emblem gloves as offset piece.
