and if you look at the fight of the scion against gaius in the V1, Thancred act like a ninja or thief, throwing knife, jumping around, Cutscene don't means anything.
other point, when i say the lore states that gun is a recent discovery in eorzea is true, check the lore. (and i'm not talking of the gunblade)
another point, yoshida did states that from now, when one class is added they will bring 2 jobs (like for the arcanist/summoner/scholar) sadly for now the jobs for the MSK are Corsair and... well i don't see another jobs that will fit the actual situation of the lore of the game.
i did read someone say, that DoW are more present than the DoM, sadly it's always the case, more warrior class than magic, check the old game of the series. the number of pure magical class are always less important.
without forget that actually we have 5 ranged for 4 melee. and if we look from a dps point, 3 ranged (brd/blm/smn) for 2 melee (drg/mnk). without forget that most of the time in the team, you bring 1 melee for 3 ranged dps (not always but most people tend to do this.)
ps: for the cutscene of thancred and all
