Like a growing dislike for the wizard after seeing how easy the fighter is.
Don't worry, the Sorcerer and Bloodmage are better, though they're both more hybrids that balance melee combat and spellcasting. The best "pure" spellcaster in the game is the Assassin; it's not obvious, but with the right approach you can turn the Assassin into the most effective and reliable fireball-spammer in the game.
Anyways, keep us up to date on how you're progressing (or if you have any questions). I'm always interested in hearing the perspective of new players and I love giving advice.
