I really like buffing Wizards. It was especially good in my PK-happy party. Nobody wanted to kill the guy who was making em stronger every day. Shield, Fly, invis... All are really good. the animal buffing spells are really good too. Once you get to a high level, there aren't as many buffing spells, so you'll become a pretty much normal wizard at 10+ level. If you're gonna convert to 3.5 though, don't be a buffer wizard, because allthe buff spells are getting nerfed.
