This is why I would like to have a guidline that says how many "points" each profession is worth. I did something like this for the professions and the races for my work on making the character creation process more like Shadowrun, and for making a levelless HARP.
As far as I could determine, the professions (and the races) did not balance out. No horrible imbalances, just not fully balanced. (One of my more prevelant gaming buddies was a real monster about balance. Everything had to balance! If he was interested in a game, really interested, and he got it, then there were some small imbalances, he began to hate the game, just over the imbalances. So, I go into the trying to balance things when GMing.)
