Instead of a question, i have a few suggestions (sorry if these has been made before, im too lazy to look it up and sry too if this is the wrong place for that, just ignore it in that case
-how about making the skilltree resettable at any level through the skill instructor NPCs found on nearly every map, with the fee increasing the higher your lvl with the lvl 70 price maybe just as high as a reset book would have cost (or how much you see fit)
-why not make turning into a kid and back to adult DB wishes instead of kidclock?
-change the mechanics of flying: Make floating in the air and going at speed 1 consume no AP, make flying at speed 2 consume AP regularly and airdashing consume them twice as fast? That way you wont fall down on a group of angry mobs when your AP runs out but just stand still in the air
-alternatively to the above, just reduce the AP consumption so you can fly longer, OR even make airdash consume EP like ground dash?
-make the GreatNamek and PureMajin transformations automatically activate their 2 skill at lvl 1/4 or 1/5 respectively (to increase their lvl above 1 one would still need to spend the amount of SP) to make it more fair for those classes
-look at the symbols for crane and turtle roshi (those you see when in party or friendlist): Doesnt the turtle symbol kinda look like a crane's wing, and the crane symbol like two hands charging a kamehameha wave? Maybe they were accidentally switched by the taiwan people? xD
Ok, thats all i can think of right now^^ If its not possible or stupid just dont do it
