Remember, this is 200 years after Oblivion. I see Racial skills as a cultural background- and if this is the case, then the skills almost certainly would have changed after such a long period of time.
People have made that clear and of course it's possible for such changes to occur in 200 years, but I think the point is here, from an AUDIENCE perspective, it's a very sudden and drastic change in "characters" we know and love.
It would be as if the evil antagonist in book one of a series is suddenly a nerdy sidekick in book two with little attention, explanation or acknowledgement provided for the change. Redguard have gone from hating the crap out of magic to being on of the more frequent users of it, Imperials are no longer the reasonable guys and Dunmer lost their fire-sword-bow combo.
It just seems like such changes at least require some form of explanation OR as an alternative, a more gradual, visual change over time. Again, Redguards -LITERALLY- pulled a complete 180, going from Trayvon being an oddity for the mages guild and that one necromancer fleeing Hammerfell because they wanted to kill him there, to now where they use it daily and look at us, the audience, and seem completely clueless as to why this surprises us.
