I think you should be able to get spells and then if you want to change them you get all your training points back for a cost of 6000 gold or something like that because it gets boring doing the same thing from your second school also I think it would be a great new thing for Wizard101! :)
There should be a quest or two that allows characters a free character reset point throughout the game. There are lots of stuff that players can spend crowns on other than reset points. I'll personally be a bit upset if we don't get a free reset upon the release of Celestia as everyone has expected we would recieve when it came out for a long time.
