I actually agree that Wish is overpowered, especially if you have any intention of using epic spells. If you stick with the standard levels 1-9, Wish being the most powerful spell out there, then it's OK. I still don't like it flavor-wise, but I'll get to that in a bit. If you're doing epic level spells, though, it seems strange to me that a "lower-level" spell has more power to alter the course of reality than the supposedly epic monstosities your 30th level wizard is throwing around.
Really, though, the problem I have with wish is that it doesn't seem mythic enough. In most mythologies where wishes are granted, the wish-granting creature can't grant its' own wishes. Granting a wish is a boon that a powerful creature gives to someone worthy, rather than a tool for the creature itself to do whatever it wants with the cosmos.
That's how I've nerfed the wish spell; you cast it as normal, with the 5000xp hit, but you can only use the spell to grant OTHER PEOPLE'S wishes. Your buddy could wish that you were smarter, you cast the spell, and you get the +1 inherent bonus as your buddy's wish is granted. But you have to trust the other person; you are putting the power entirely in their hands.
Does this work in practice? Couldn't tell you, I've never had a game get into high enough levels where PCs had access to Wish. It works great for NPCs, for what it's worth...
