Something like that, but probably not that exactly.
The story of Leeroy didn't mention him trekking back to the teleportation point, and really anchoring this all to a location would undermine the freedom trying to be presented. On the other hand the story of Leeroy also implied he did in fact spend the whole party in the Discipline of Magic.
I think you misunderstood me. The teleportation points function on Aetheryte. I'm talking about taking that same type of technology and putting it into a portable device that changes your clothes, not actually using the teleportation points to change clothes. I mean, I guess that's possible too, but that's not where I'm putting my money.
But there must be some restricting factors to gear swaps in play here, because it makes no sense to categorize things into Disciplines if you could access everything freely.
It could be that there won't so much be penalties as a lack of benefits. Go back to the AP system (the "BLU system") present in a lot of FF titles and completely separate games where you set abilities that you've learned, but don't have access to all of them. Maybe you'll have to set your abilities, and they'll stay set regardless of switching weapons/armor.
i.e., you've set Cure and Fire, which you previously learned, to your Gladiator. Switching gear to a mage won't actually allow you access to new abilities-- you'll still just have Cure and Fire. Switching will just allow you to work towards unlocking new spells (presumably you can't do it mid battle).
Something like that could conceivably nullify any advantage to changing jobs for combat purposes. Though it would probably be easier just to impose a penalty, which would be fine with me.
As for it making no sense, well, I mostly agree. It allows you fluid access to rigidly defined jobs (like in FFX-2). While that system can make sense, it's kind of silly, and I hope that's not what they're doing.
Ok, now we're going to get slash fiction of Wint x Kachi somehere... rule 34 and all...
Never confuse your inference as the listener for an implication of the speaker.
Good games are subjective like good food is subjective. You're not going to seriously tell me that there's not a psychological basis for why pizza is great and lutefisk is revolting. The thing about subjectivity is that, as subjects go, humans actually have a great deal in common.
