I belive that the time limit for SSJ was because of the energy leakage, it is hard for the body to contain 50x more energy than it is used to. Mastering the form ment 0 leaking, which massively increased power and made the time limit infinite, only limited by how much ki you used while it was active
good chapter and story remains excellent and looking forward to the next chapters. just the whole matter of the dream still doesn't come down to me and discouraging. i think do kara and raven in a relationship with mc in real life/'physical' (without all that dream stuff) or do nothing and keep mc and kara. And look, I'm in favor of the first one (kara and raven), this whole 'dream' issue and situation, to say the least is 'questionable' in a bad way, the only bad point I have with your story. anyway, my opinion, not wanting to criticize your work.
yeah focusing on mastering super saiyan 1 is important how about super saiyan on and off training where you train to use supersaiyan only when hitting or mastering the art of going ssj without the strain, and going off , with such ease its like wearing a shirt, and goku and gohan did basic training as their baby steps first and foremost and it took them almost a year worth of training non-stop to get to that
