About Materia.

I just thought that it would be better that the road of making a materia be more complicated and Harder while melding it be the other way around,

like if i got a materia that i worked hard on i could meld it myself without the help of a crafter
.. like in FF 7

Go play FF7 then.
Do you understand how detrimental your suggestion is to an MMORPG? When people only have to rely on themselves, I have to wonder why you're bothering trying to sell an MMO.
