Is there a conspiracy for lvl capped players to ignore materia?

[Ferra]

I mean...If there's an NPC it wasn't made known to me. So maybe that's part of it or it's a higher level thing!

But that's the two ways I was told Materia can be melded and both seem unimportant at the current time.

The game even tells you there is an npc for it in some side quests at around lvl 30. So you skipped it is what happened.

Those NPCs weren't always there, its possible for veteran people to not realize they exist.

Regarding the OP: I personally don't care enough to do it. I'm not raiding and in dungeons it doesn't really matter anyway. (call me lazy if you want, I don't really care)

I remembered wrong. Its a an ARR msq quest. So you just didnt bother to read what they were telling you.

Neither Life, Materia and Everything nor Waking the Spirit refer to the materia melding NPCs. The former is part of the MSQ before Ifritt and that one only tells you to learn how to craft (assuming Gobbiespeak didn't make your eyes cross) at least according to one dialog transcript I've just read. The latter is a blue quest that opens up materia transmutation.
