Peacock charm was level 30 and it is awesome all the way to level 75. So that proves your statement wrong. I know there is some new neck piece with accuracy +12, but as I said before we don't know the time or money required to get that stuff so it's entirely possible that PCC is still the best economic solution. And +2 accuracy really isn't going to make or break you. That's just one example.
I guess I really only care about stuff for Blue Mage so that's what I focused on. And from the list I only saw a couple things that I would consider an upgrade. Weapon, Str rings, a leg piece that probably beats Homam, that's about it. Nothing will beat BLU AF+1 body for casting spells in, for example, unless it has BLU skill +20 or something. But I don't see anything like that. I'll have to wait and see what the AF3 looks like.
