Low levels are all about learning your class and that's it. Class balance is hard enough for Blizz to maintain at lvlcap. I seriously doubt your QQ will be heard. Until you level yourself past whatever bracket you're getting farmed in, try dungeons or questing...or I can just keep enjoying smashing your face with my shiny penance balls on my baby priestlings. ^.^
Simple. Hunters in twinks are OP in some cases, I agree. Now pit that hunter, or any other class in game vs a twinked disc priest. Watch what happens. Answer? Disc walks off after getting 18 HKs full mana, top HP and still a retarded shield on.
