You're really overstating that it was a tank, many NPC's that are jobs that aren't tanks do tanking in scripted encounters. Do you think White Mage, Arcanist, and Monk are tanks? Because those characters tank things in scenarios all the time.
I think it's far more likely to be a coincidence, yes, because as a job tease it's a pretty weak one for all the reasons I described before. If Gaius was a job tease, then he's been a tease for it for over 5 years. With Regula, Nero, and Fordola also being teases for it.
Still a stretch.
Putting aside the creepy stalker aspects, I was regretably wrong about Samurai, but that's not because my reasoning wasn't sound, but because Yoshida opted to go with his personal preferences over the way Samurai was represented in past Final Fantasy games. I trusted Yoshida to stick to honoring what past Final Fantasy games had done but instead he went with his own personal tastes as revealed here (bold emphasis mine):
So I'm actually glad you drudged that up, because see, I learned from my past mistake of believing Yoshida would follow something that made the most logical sense, but instead he opted to make a decision based on his personal preferences first and foremost. I didn't listen when Yoshida talked in interviews before about Samurai and how he always felt it was a DPS, and how his idea in his head about a Samurai was a robe wearing iaijutsu master. I rejected what he said he was likely going to do because it didn't make sense to do it because it wasn't how Samurai were depicted in the vast majority of Final fantasy games. But alas, he did it.Yusuke Mogi (Lead Character Concept Artist): When I heard we were doing samurai, at first I pictured the armored warriors from FFV. But Yoshi-P preferred the simple, kimono-clad look, and so we ended up with a cultural and visual aesthetic that reflected this, with the majority of NPCs dressed in kimonos.
Q:What were you going for in choosing kimono-clad samurai over armored ones?
Yoshida: I wasn’t going for anything in particular—rather, that’s just how I’ve always pictured samurai. I enjoy the films of Akira Kurosawa,* and his samurai are always dressed that way. I think of armored warriors more as shogun or warlords, rather than what we would call “samurai.” For our international audience as well, I figured kimono-clad samurai would feel more natural to them. That might not be true for longtime FF fans, but I was also hoping to appeal to the masses and draw in large numbers of new players as well.
So that's why, when I see Yoshida say things like he'd maybe do a male counterpart for a Viera, and that he finds male bunnies weird, and that they put in lore pointing out how male viera might as well not exist to the outside world, and then completely refuse to show or even acknowledge that male viera are coming, I tend to put more merit into his words.
So it's ironic that you'd drudge that up as some kind of a "gotcha" moment, because it backfired on you pretty bad by revealing that you are the me from back then.
Will you?
