How can you all be so sure that Mystic is so much more powerful than SSj2? I tried to figure it out, but before I got to see Gohan do anything worth watching he was in a massive crater with a concussion. Mystic Gohan is like SSj2.5, not like SSj3, not like Ssj2. The sad truth of the matter is that Gohan peaked at age 12, and he was never more powerful than he was in the final battle with Cell. He may have had a higher power level when he went mystic, but the boy had forgotten how to fight. Gohan can transform at 1,000,000 for some reason, so let him transform to ssj2 and mystic faster than everyone else. Instead of giving him normal multipliers for those transformations, cut them in half, to symbolize how quickly he turned into a loser as an adult. No, he wasn't all that bad, but he wasn't all that good either. Give him power, but don't overpower him.
Mystic is no SSj3.
