so im running a new game, set in 4e. the premise for the characters is that they r dragons. i had them also make 1st lvl characters that is what their dragons r in humanoid form. their charcters just became aware of their draconic selves and im wondering how best to make sure the game doesnt get over balanced. im thinking that the ability for them to turn into dragons is either an encounter or daily power to start out with. any advice as to this and maybe any other ideas would be more than welcome to hear.
