If you look at a fight that is mostly single target, you'll see hunters hanging out right in the middle of the pack DPS wise. It's known that Hunter's absolutely suck at anything multi-target, those fights bring down our spec score and make us look awful when all you choose to look at is overall numbers. We need some mechanics that allow us to compete in these types of fights without throwing our single target damage completely out of control.
That and Afflication/Fire need to be tuned. I feel that specs that have the ability to completely destroy meters on multi-target fights shouldn't be topping them on single target fights as well.
