We could also looking into what has been in development for the game since day 1. and I don't means FFXIV:ARR. I'm talking FFXIV Alpha back in 2010. I can't find it anymore but the Japanese player that made FFXITool made FFXIVtool for FFXIV. they had a page on their site which detailed the job/class list from the Alpha. It listed out a bunch of classes and the weapons they used. The class list was pruned when the beta started.

It included these jobs that were not put into the game at the time.
Arcanist -
Assassin -
Bard -
Enforcer - Clubs
Fencer - Rapiers
Flayer - Whips
Musketeer - Guns
Mystic -
Samurai -
Shepherd - DoL raising pets
Stavesman - uses staves

also in the list were

Gladiator
Marauder
Archer
Pugilist
Lancer
Conjurer
Thaumaturge

I believe Arcanist became SMN/SCH
Mystic is likely AST
Assassin is NIN
Musketeer is MCH
DRK isn't even on the list. Unless it is using the Stavesman class, which is somewhat reaching. I don't know what stavesman was supposed to be other then they used staves.
Bard got merged into Archer for the BRD job.

This leaves use with Enforcer, Fencer, Flayer, Samurai, and possibly Stavesman

Fencer is becoming RDM, which is the only thing we have confirmed until the next fan fest.
as to which job spiderman is implying I don't know. could it be Samurai? or could it be Flayer?
