Fair enough. What about a racial intolerance chart?
In 3E, every core race seemed to - more or less - get along. I'm sure this provides the social lubrication needed so a party of PCs can be of any race and not have to delve into bickering based on "accurate" roleplaying. That being said, I think some decent racial antagonism could add to RP aspects, and not detract from them. It seems the table has been set to allow such a chart (eladrin vs. elves, dragonborn vs. all, etc.)...but will anyone dine upon it?
I don't see the developers taking the next step and providing a context wherein everyone is not everyone else's friend. And that's a shame, I think, because some of the best fiction you can find uses such racial norms as a compelling springboard toward an interesting social dynamic and - more often than not - a "realization" somewhere down the road that everyone should, afterall, get along.
But I think that point of harmony is best reached after characters spend some time on the road saving one another's lives.
