I don't know how your wizard achieved such amazing heights, but if I was DM, I would tip the scale back towards the fighter. My 23rd level dwarven fighter with the ax of the dwarvish lords could BARELY do damage like that, and ONLY if he crit at least once and hit with 4 attacks, which I don't think he ever did. IMO, there's no way a dwarf wizard should be consistently doing more melee damage than a fighter. I think it's an interesting concept, but to me it really underscores a huge problem with your campaign. I would be pretty upset if a wizard was outdamaging me (were I the fighter of the group) with any modicum of consistency. Even with Falselife you should have far fewer hit points than the fighter (lower hit die and con, even w/false life, it should be lower). Also, beware greater dispel magic! Also, what happens when all of your buffs are dispelled and you can't immediately rest to get all of your spells back? Oh, and nothing against your group or this concept...it's just that I don't like the already powerful wizard overtaking a fighter's place, and as DM, I would make as many houserules as needed to prevent that from happening (on a consistent basis). Just my opinion though. I love fighters...always have...and I like to keep them as the masters of melee. I think it's fine situationally to have the wizard beat out the fighter (against the RIGHT foe, with the RIGHT spell buffs)...but if as DM I saw this gap closing too often, I would start giving the fighters more bonus feats or give out less wizardry magic items.
I'm not trying to take away from anyone's enjoyment of playing a melee wizard...I say go for it. It's what I love about 3.5...all of the available options...it's just that sometimes the rules allow for things for which I don't agree, as with the above scenario. I hope you were playing an epic campaign and your dwarf wizard was something like 30th level.
