In DBZ, Saiyans managed to overcome their limits by giving in to anger and frustration (Super Saiyan 1-3), but in DBS, it's been the opposite. SSG required six pure-hearted Saiyans, who'd managed to overcome their inherently wild nature. SSB also requires a calm mind. And then there's Ultra Instinct, that literally requires you to be so calm, your mind goes blank, leaving your body to react on its own. In other words, DBS has Saiyans going against their savage nature to surpass their limits. DBGT did something similar with SS4, which requires a calm mind while going back to the Saiyan roots (Great Ape).
What do you guys think of this change? I found it interesting, but I'm not sure Toriyama intended it this way.
