Is this going to be like an X-Men sort of academy? Or will people allowed to be more exaggerated/crazy like Teen Titans, Avenger's or Superman?
it runs the risk of becoming too powerful so that the RP simply can't work because the plots are all too easy to solve without divine intervention restricting the characters.

Oh good, someone who had the same question I did! :P
Allow me to answer as I have just drank some yummy coffee and showered!
Your answer is yes! Now let me expand: it'll be a lot like an X-Men sort of thing. Your characters would be brand new to the academy, for one reason or another (maybe you got a scholarship, your family just got word of it, or you finally saved up the money to afford it) The idea I had is that your characters would be pretty new at your skill, you'd be compenent enough to not blow yourself up, but you're no Superman or Wonderwoman. Think more like Rogue, a young Storm/Cyclops. 
Hopefully I answered your question! :3
