Really if anyone quit because they can't play a new race in the gender they want, I would say SE is better off without that few $... The headache isn't worth it.
If you think about the time it takes to make a new race. Remodel all the gear... Making quests and lore. The pay off is very very little.

I will not be switching. I'm happy for people that do and like it. But I would take content over customizations.
Jobs are content they all play differently.
Quests are content.
Dungeons are content.

Glamour is content...
But Glamour on any male or female character is the same content...
