The things i didn't understand really.
1) Young Roshi... combining Krillin and Roshi to save time... maybe?
2) Shapeshifter... what? Why? That's like the one thing that wasn't in dragonball. Is this just so Goku can be fooled and have the balls taken away from him without physical confrontation.
3) Why are the dragon balls apparently powerhouses on their own. Isn't the wish thing good enough?
