Spiritbinding = Ex?

[AmandaHuggenkiss]

Maybe I'm reading too much into it, but I took "1 spiritbond point" to mean "100% spiritbond", as in you can keep using the weapon to improve the spiritbond further, and possibly get better materia from it later. Or maybe spiritbond points apply a small buff to the weapon to keep it relevant if a player doesn't want to trade it away for aesthetic purposes. Or something.

It seems hard to believe that they'd make it so you can't trade away a weapon if you use it at all. That sounds like something that would obliterate the trade of anything except consumables and crafting ingredients.

I read it as this:
Craft/buy gear.
Earn 1 exp.
It is now untradeable.
