Even Levitate has a negative effect on the game in that it can make other PC's climbing skills a bit redundant. What I suggest is the Fly spell is removed and Levitate becomes a 4 MP spell. I'd be okay for it to be removed too, but I'm thinking of the situation where the entire party has to get up a cliff. It's probably better to allow Levitate in some form than have specialist wizards needing to learn climbing.
Then add a 2 MP Leap spell, and a Feather Fall spell that's maybe only 1 MP. I think Leap shouldn't allow the recipient to automatically control the jump or nail the landing, so making it a touch range spell would allow it to be cast on someone else who's more dexterous. For Feather Fall, with the AFF casting roll it's good drama using it under pressure on someone else in mid-air, so I'd give that one a range. You should get a bigger penalty casting it on yourself in mid-air though!
