Well they mentioned several times that nothing has been balanced; so I'm not sure one should be surprise at the total lack of balance between classes and skills. I'm not too sure how much feedback they want (at this point) with regards to balance issues. That is a very open comment they might want a lot of feedback or just a little. Also things might be unbalanced in one direction at low levels but as the game scales things might balance in the other direction at high levels. I sort of like this scheme in some games where you have to give some thought as to whether you need something now or later.
