Should you have to be wearing gear you attach to for Materia making?

[Peregrine]

the gears has to be worn because as they described it you build up affinity with the gear to convert the energy built into materia. How do you build up affinity with gears lying around in your bag?

They code it like that. Gee, that was easy. How does that work in Eorzea? Well Aetheryte attuning. The 12 allow it.
There you go.
See, the thing you fail to realise is that they can do whatever they want. THERE IS NO SPOON.
The attached gear doesn't even have to be in your inventory at all. See? Outside the box, man.

Argue why it has to be worn to be attached to. Again, it's just a bad idea that intitially sounds like it's naturally got to happen when it DOESN'T.

What you're saying is you have no response to why gear would have to be worn to be attached to. Or that you don't like me. Or that you don't want to provide relevant feedback.

Oooookay so if you can't tell me why gear should have to be worn, and I just told you precisely why that's a dumb idea, then case closed.

Gear shouldn't have to be equipped to turn into materia unless someone can provide any more relevant discussion than, "you don't know" yeah I pretty much do and it's going to be hamstringing itself by confusing Matsui's goals with counter-goals that conflict.

Don't get me wrong, that's on par with the way things have gone thus far, to design a system that antagonizes everything about the OTHER new system.

But come on now. Time to straighten up and fly this ship right. Negative on this feature. Don't do it. Doooon't do it.
