You can't "lock" something that doesn't exist.

Humor me then, what would you call it when a player race only has one available gender?

An all/ only Female or Male race.

the semantic problem is people who use this term incorrectly trivialize the solution.

the response is frequently "just unlock it", "unlock it already" when it really should be, "we want 2 complete races added this expansion instead of 2 halves". it sounds much more unreasonable to ask for two races to be added to one expansion.

it allows them to be entitled without sounding like it. it allows them to make what would normally be an unreasonable demand sound more reasonable.

maybe some people feel like we're owed two races since Stormblood didn't have one and that's probably a discussion worth having but we rarely if ever talk about it like that because semantics dictates that we just talk about unlocking what's been locked.

This really is the reason behind this and doesn't get enough focus.
Which is why I casually point this out when I come to these forums. It's alarmist in that it makes others think something being taken away from them and makes it seem that it can easily be fixed.
