If I wer you, I would go with the older enchants because The level 85 one scales to 9 agility and 5pvp resilience which is pretty good, but the older ones like the level 80 and 70 ones I think are the best which are like 26 attack power and 16 hit but they don't scale worth a crap at level 60+ lol best of luck!
arcanum of ferocity scales down to 26 ap 12 hit, will be changed in WoD to 13 AP / 12 Critrating
Hunter ZG enchant would be a lil bit better dooesnt scales, atm 24 ap 10 stamina 10 hit, will be changed in wod to 12 ap 10 stamina 10 crit
