first off no one likes 4th edition =P lawl. next gwf could go either way as dps or tank since there is a tank tree and a dps tree =P I still dont have any problems with my dps and as far as the gwf goes, it is more of a late blooming class, lots of good perks the farther you level.
you are correct. with that said, i for one really haven't fount it too hard to level. hit level 30 and haven't been defeated much noticed better dps numbers when i fixed my gear stats
