Materia system decipher

[Narctiss]

Post updated with quotes!

I had to correct a couple of things I originally wrote but most of it is the same. I think everything is covered.. I may have gotten mind lost through info trawling, so if I missed anything let me know.
No worries either, I read Rein's JP translations (and the French translations too! One of the quotes is from there. =) ).

Rare/ex equip will transform on rare/ex materia and they will be able to be attached whit materia

I haven't read or seen this anywhere. I don't read the JP forums (I can't read JP!), so I can't say for sure or not. Based on the info from Reinheart, Perrin_Aybarra, the English Dev responses and the info given on the lodestone that hasn't made any sign nor hint at it, I'm more likely to believe that as rumor until confirmed one way or another by an official source.

If they're trying to make it 'fair' by keeping normal crafter made gear up to the quality and usefulness of the NM/raid gear by allowing it to have materia, it'd seem odd that they'd go ahead and allow materia to be added to NM/raid gear too. The French dev translation quote covers that by saying NM gear won't be able to be 'enhanced', meaning normal materia or this rumored 'ex u/u materia'.
