Female Hrothgar as a playable race. Show your support!

[Fland]

I don't think it's guaranteed to be during Endwalker just because the existence of female Hrothgar was assured alongside the Viera reveal.

Even if they aren't coming until 7.0, I think the dev team have learned their lesson to not be coy about the fact that they are definitely coming at some point.

AFAIR they never announce something is coming on fanfest keynote for a later expansion. There might things that they gave vague answer about like "I'll talk to the team" or "We'll see the player's response" during live letters, but not in this case.
It's not a 100% guaranteed of course, but I'd say the chance femhroth is coming sometimes during EW is higher than in 7.0.

they even mentioned they thought about releasing them together (holding male viera off), but then decided to implement them 1 by 1. as iscah already stated, fem hroth didn‘t get „delayed“, we just got male viera earlier.

That's not what I got from what he said tho. We didn't get male viera earlier, having it on 6.0 is their plan. They just couldn't get femhroth finished to be released together with male viera in 6.0. So yes, in this case femhroth is the one that is "delayed".
