Is your creator made heros with hp regen going only to the amount that you have chosen it to or it can also go to the amount you have from other heros?
Oh about the AP regen you can look into the Hero steel code but as your now remaking it to 1.2 you should find it on the new includes.
Oh and about kd's. you should put in option to have skills on kd. For example: do you want a kd and then you can tick a box behind every power. those boxes should be enabled only when the power has been chosen and the kd button has been chosen. What do you think.
