if the purpose of the current system was to get rid of old gear. Then we could keep that. Have the materia we we currently get from gear be used for crafting/creating the materia that this thread is talking about. You have to collect so many bloodthirst "gems" to create an actual materia that was able to be leveled, swapped and what have you.

It honestly doesn't make much sense how it is right now. The essence of whatever your converting is stored into a materia and it boosts a specific stat? The stat has nothing to do with what was converted more times than it does.

But that's just me. I like to suspend disbelief when playing a game and blatantly illogical things keep me from doing so.
