Why only one materia slot for weapon, armor, and shield? Possible Alternative.

[Viladin]

Hello, I was wondering what the design logic was behind this. I understand limiting materia to those specific types of items for easier management, but why can we only equip up to a total of specifically 3 materia? Why can weapons, armor and shields not have additional materia slots?

Perhaps, as a possible alternative, materia could be made use of through Special Materials. There could be one special material that's designed specifically for materia, lets just call it "Materia prepared metal" for now to keep things basic. And that could have an increasing cost to allow 1, 2, or 3 materia slots to the weapon, armor or shield. This way, if players wanted to focus more on materia and less on static, unchanging items for their final fantasy game, they could do so with reasonable balance because they'd be investing a lot of there gil in the special materials needed for materia slots.

And even further, unique special materials (Such as say Crystal or Mythral or Adamantite) could have their own inherent number of materia slots.

Thoughts and Feedback?

Reason being because of the abuse of enchanting weapons/armor THEN applying materia (which also acts as enchantments). At the beginning, there was a time where you can slot multiple materia to weapons and armor, and that got extremely overpowered.
