True, what msot people have problems with the hunter, including high level hunters, is solely because they aren'tgood at playing the class. However, this doesn't mean hunters don't have a host of their own problems as a CLASS. We are a ranged attack class with less ranged attack powers then any other ranged class. We are a pet class with less pet powers then a warlock, however we have slightly more "control" with our pets. Then again, we have more micro managing then a warlock for that control.
We are the only class with a "Dead zone" and area we can not attack into between our range attacks and our melee attacks. We have that spot without any way of getting INTO or OUT OF that deadzone spot from our opponent to attack back if they won't let us.
We have problems with equipment specifically tailored to hunters as a whole. We have problems with some pet scaling, not as much as some point out because they are picking the wrong pet for the wrong job, but there is a problem.
We have bugs galore from pet run speeds getting stuck at lower then normal, +attack buffs not doing anything which makes powers like aspect of the hawk and hunters mark nearly worthless, and we have a severe lack of melee prowress.
Those ARE class problems unique to the hunter that all hunters must deal with. No matter how good a player is, they can not make those problems go away. There ARE alot of "problems" people complain about that really aren't valid because they are induced by play style and not by the game to everyone.
Then again, hunters aren't the only ones with problems. Hunters are just last on the list, if there is a list, of getting their problems fixed right now.
