Orrrr SE can just make NIN a whole new thing with barely any ties to MNK.
Cuz like they are hyping community with teaser info and the fact they r taking a long time with it.
Cuz its ffxivarr, not ffxiv or ffxi
so all this logical theorycrafting and speculation could end up making us look like goofs when SE drops the nin patch on us lol!

But who knows.....
Anything is game lol
