I'd like to just throw an idea out there that has probably already been mentioned I'm just to lazy to search ;-). How about a way to save masteries/spells. Doesn't have to be server side at all maybe just make sure theres no way to glitch it, but basically a text file that is saved client side that will remember which spells and masteries have been chosen for that hero and save it. Even to go as far to say if that sounds more hassel then its worth it shouldn't be to hard to implement a system such as the rune pages for masteries/spells. Thanks for your time in reading my suggestion.
