But, let's say I want to try and make a Thayan, there's no reactivity to it, so there's no real flavour to the Human side of things.
I'd have thought something like that would be better handled by specifying a home location tag for your character, rather than by having a subrace? Of course, we don't know if the game is going to be able to handle any other home locations for most races other than Baldur's Gate, which at least at the beginning of EA seemed to be assumed to be the home of any non-Underdark races, but it would be great if we did have some other options. I just don't think introducing subraces for the different countries would be the best way to accomplish it.
