Yeah, I typically play CHA classes(I prefer spontaneous spellcasters for example) and feel locked in to half elves and Drow. And I can't make av Drow look how i want because there's not enough skin colors in the true black/Grey range. It's all weird shades of lichen blue/Grey or purple.
You NEED 16 in primary stat. I hate uneven stats, too. Not enough for the next modifier feels bad.
Uh oh. Be careful saying such things lest you attract the "you're min-maxing/power-gaming if you match racial ASIs with important class ability scores. Just play a mechanically worse character" folks.
But yeah, rolling for stats (again which Swen said is planned) will help in creating such characters. As would:
If Point Buy let you buy up as high as 18, and down as low as 4 (you'd never get more than 1 point back (or possibly even none) from going below 8, but the cost of going up would continue to increase by the same step beyond 15, so it couldn't be 'abused'), I would be less critical of it, personally.
+1 to this because why not? I've highlighted a part I think is incredibly important. Otherwise you too strongly incentivize heavy stat dumping.
