I care less about balance and more about flavor.
The more differences between the races, the better.
There should be enormous conflict and racism between the races in the setting. That's what world-building is all about. That's part of what gives a setting depth. Right now, things are going in a terrible direction. The push to make everyone the same removes the art from the game and leaves nothing behind but a boardgame in its place.
More and more, the races are being treated as costumes.

The tieflings are tainted by something devilish. That should be reflected in them. Half-orcs are half monstrous, which should be reflected. They are also larger and biologically stronger. That should be 100% reflected. Elves live an enormously long time. They are generally considered more beautiful and closer to magic due to their fae heritage. That should be reflected in their portrayal.
Instead, we end up with a setting where the dishwasher at the local inn could be whatever. The courier could be whatever.
It's just bad. I'd like to see someone at Wizards with a little bit of courage and vision. I bet anything, if this were done in Faerun, it would first be met with a large outcry from a very vocal group, throwing around crazy accusations about society and such. And then, when all of that was ignored--as it should be--the real consumer base would be thrilled and massively entertained.
