I agree with what Ethys said on his YouTube channel about those pots. They kinda nerfed some aspects of the game and story to appeal on those who want to lvl faster. Look what happened with the Primals and the Awaking Primals story arch. It got shafted from the MSQ and became an insignificant side quest. If they gonna nerf everything to appeal to those in hurry for lvling then implement the potion at a high price for those willing to skip and let me have my compiling FF experience without reducing the core experience for us who want to have the traditional FF RPG experience.
