Thank you for the reply. I completely support your idea to change this system, but to be honest, the anticipation for this "megapatch" has been going on for about a year now.
Suggested fix (unconfirmed): Toggle the switch located at the bottom-left of the map once you have all the Fragments and Gold Databanks. Use your charge shots matching the color element of the final boss's current shield outline to defeat him.
