Fun times, eh? I can see how it'd be upsetting but there's no point on blaming the crafters. The game has more crafting classes than DoW/M classes. Of course they're going to control a partial amount of the economy. Did you expect with so many you'd be able to control it yourself just by finding things?
What's the point, a lot of new gear is rare/ex. You wouldn't be able to sell it anyway.

Besides we just found this out today I believe? Or earlier this week?
I can't think of any reason for why this would be in the first place. Except that the new items might have new stats or ID number that makes it possible to attach materia while old items don't have this?

:S
