You're joking, right? Enhancement is far worse than almost all of these specs and they don't even come close. A balance druid, affliction warlock, fire mage, unholy DK, and many other specs out DPS enhancement with ease almost every time and even at lower ilvl of around roughly 10 ilvl difference. That should never happen if things were balanced. Enhancement has been one of the most ignored specs for a long time now and they honestly should have kept the windfury bug that was happening at the start of this expansion because it at least made us competitive DPS unlike now.
so what this tells me is... Rogues need buffed! :D
