I'm an old school gamer and dislike the direction 3rd edition and Pathfinder took in making every single monster race playable. That said, it's just the reality we live in now. If they add in all the freak races, so be it, but please focus on the core races as a priority. Gnomes first, then round out the rest.
Also why the hell is Drow not an elf sub-race?
have to admit, i wondered that about drow too lol, i assumed just a quirk of the engine.
