Question about Possible Chemist/Apothecary?

[SweetPete]

I don't remember which interviews but Koji and Yoshida talked about problems adding Chemist before so they split it off into MCH and AST: MCH took the gun weapon and AST took what would have been their Mix mechanic.

I know I remembered them talking about it in some case. That was years ago though. I hope they found a way to add it in 6.0.
