I really don't understand this either, honestly. I have no problem with speculation and yes, it can be fun, but...

I legit fail to see what it is that even makes anyone think that the lady in red is a dancer? Beyond the outfit. When I first watched the trailer, for literally 2 or 3 seconds, I thought, oh, could this be a dancer?

But that went away as SOON as the camera began to zoom in, and we got a decent look at her. And this is why I don't get all this "could be a dancer!!!" fervor: there is absolutely nothing that she does - no single attack, movement, form, anything - that says "This is a dancer. This is NOT an East Asian-style martial artist".

We may yet get dancer. I don't think it's impossible, but the woman in the trailer is in no way confirmation of the class coming to XIV. If we DO get a dancer class, I'd be surprised if it looked/played/felt that similar to Monk, anyway. I'd figure we get something that has far less focus (if any) on hard strikes, and more on pure movement. Of course, we also don't know if it will be DPS or healer (or even tank! In theory we don't know WHAT it will be, but I do find tank less likely).

Though that is another thing I've seen that I don't get: assumptions that some people seem to have that DNC (or RDM or SAM, for that matter) absolutely will be a certain role. Or that if it ISN'T that person's role of choice, then that's the final straw and they will be quitting the game. I mean, really? You've been playing this game for this long, but if RDM is a tank or DNC is a DPS or (whatever class/role combination it is you don't like), then that's it, you're out? Okay then.
