I think the main difference between this and aion, is the materia seems like it will be fairly easy to obtain. Just level up and use up your gear. I suppose this is why they are killing parts, they want base gear to be very cheap, and in high supply. So hmmm lets see, where will the cost be?

NQ gear will be super cheap.
+ gear.... i dunno how cheap that will be, depends how easy it will be to get +1 mats since it is skill less now.
materia? probably pretty cheap, except maybe whatever is the + version of the highest level gear, since you cant get it easily since no gear over 50 exists

catatlysts? might be expensive.... every materia attempt needs it. and it will probably be in teirs, If so, only really high level gatherers can get it, and there aint that many gatherers, and though i havent tried it since 1.18 gathering seems to level a lot slower than every other class. Add to this that they say some nodes will have stat requirements.

Anyhow, i think what will end up happening is no specific peice will cost a lot. most gear value will drop. however the fully upgraded versions will be manufactured and sold at insane prices. That will be how most people get their +materiad super gear.

people will really hate level cap raises, and new gear with good stats after this though. Because the investment on a super slotted materia gear cannot be returned. all you can do is make it 1 materia that you have the same chance of getting or actually even less chance of getting in the case of level cap raise.

interesting
