You all know it. You do a piece of fun content only to be rewarded with Materia... We've all been there.
But why is everyone prone to feeling this way? I would say because as it is, the Materia system is extremely boring and getting them as a reward just feels like a slap in the face.
The materia system should be overhauled to be a fun gameplay mechanic instead of just feeling like a grind. Allow Materia to be unique and have unique functions!
