Mc presumably has the talent but not the understanding which can be taught/improved by a teacher. Not all rct is equal, Hakari is stated to have faster regeneration than Gojo but neither can heal others like Shoko can. Gojo mastered rct with the 6 eyes and Hakari uses his jackpot which makes them outliers. The way Shoko and the rest of the cast improved their abilities is by training with them after they unlocked it first. Unlocking it usually happens by chance but we're directly shown that you can increase your chances by intentionally trying to use it. The lawyer guy got lucky and did it his first try but Gojo had to wait until he was a teen to get it since he never put in the effort before.
Juan_Garay_0225:RCT is not taught, it is learned by itself if you have the understanding and talent to do it, otherwise there would be many more sorcerers with RCT.
You can't be talking about that silly fight between clans. Brother, Chinese novels did their job. Because of those novels now everyone wants to force a clan fight into their stories. And in this particular case, it doesn't make any sense. We don't know other members of the Gojo clan (except maybe for Uiui and Mei) so you decided to make him fight with Satoru? It's serious? Brother the story is good, you don't need to make that exchange. You are on the right track.
