No, I didn't miss the point. You're thinking the blame lies with the devs for not actively making it their responsibility to shut-down any and every speculation that is incorrect when in reality the fault lies with people being incapable of curbing their own expectations and getting carried-away with speculation. That's quite selfish. They're not obligated nor responsible to rein-in speculation just because some people can't handle being incorrect and/or disappointed. Yoshida even mentioned in one interview that if they did do Viera, they'd probably do a different race for the males.
I'm not going to go too far about "Dancer healer" because that's not what we're here about. But I will say that expecting Dancer to be a healer when in fact it's probably had less healing representation than say, Summoner in the series falls into the same mistake of making assumptions based on what people's personal preferences are. It's perfectly valid to be disappointed that the 2nd job for 5.0 isn't a healer (since one is a tank), but to assume Dancer specifically had to be designed for the healing role is personal bias. The "fault" for male Viera lies within its own fanbase propping it up as something that "had to happen" or "they're just saving it for Tokyo Fan fest!" instead of accepting the fact that it could be omitted or any current preexisting lore in XIV is an inconvenient excuse (which again, Yoshida mentions as a way for fans to figure it out themselves before the next fan fest).
Don't confuse misinformation with the lack of it. And if you're going to be upset about lack of information, go apply to the dev team so nothing is a surprise to you and you get to know exactly how everything will turn out. Its either that or people learn how to handle disappointment without shifting the blame.
If you ever find out which interview, feel free to share. I've just went through a couple of Tokyo fan fest-related interviews and saw nothing of him saying as much outside of new jobs.
