Had you suggested mirror racials for same races which can be used to make the same classes, then your point would be valid. But no, you suggested the addition of extra racials on top of the existing ones, meaning that the explained class balance would be changed.
Actually lets take a look at your proposal while we at it shall we:
Oh yeah, paladins can totally have wotf atm, right? Smh. And roflmao now I realized you even tried to combine 2 op racials for humans and giving undead shadowmeld KEKMAO man KEKMAO. At least you shouldve had the gut to give each side exact mirror racials instead of that bs. smh for the last time I hope.
