The point is that you're taking options the players used to have away from them, and moving them to the DM, who can dole them out again if he feels like it. That's not a good plan IMO, and I think I'm not alone there, especially in a salable product.
The point I am making is that you’ll never get the fighter right if you believe he’s balanced with a wizard as is right now. Whether you decide to nerf the wizard or take the fighter up you need to understand the point it becomes unbalanced.
Then you have to ask yourself, can mundane abilities ever compete with the additional. i don’t think any set of mundane abilities can ever compete with Once per day mass suggestion/teleport/wish. You could give the fighter +20 to all skill checks and it still wouldn’t matter. The only thing that might come close is retainers/henchmen and that’s not a very appealing solition for most.
The issue is that relying on the currently powered high level wizard leaves the fighter impossibly behind due to restrictions on mundaneness.
