Is Alter Self more powerful than Fly?

[PinkysBrain]

You can make the hoops to jump so annoying noone wants to jump them at all, but if they are at all jumpeable they can be jumped for those creatures which work especially well with the spell ... and when they are jumped the spell is just as powerful as if they weren't jumped at all.

It's not even just about flying ... getting +5 to your armor, bite and claw attacks and the multiattack feat is even more overpowered really for a spell of that level.
