@AceDefiant I've thought this could be a really cool feature as well, especially the idea of adding races that have never been playable on retail (i.e. ogre, arakkoa, naga, quillboar, tuskarr, saurok, etc.) and -- if nothing else -- making them available on the shop to boost DP sales.
The biggest pushback was the idea that these races would either have new, exclusive racial abilities or a mix of current racial abilities that would give players spending DP an advantage over others.
I felt the best compromise would be to give these races re-flavored versions of a current race's features (for instance, giving the naga all the same features as the trolls but re-naming them) so there wouldn't be any mechanical difference. Alternatively, give players the ability to customize the racial features of every character, allowing one active and three passive, choosing from those currently available.
Unfortunately, this expansion of content doesn't seem to have enough support on the server. Other private servers have made it work, though, so I know it's feasible. (I thoroughly enjoyed making an ogre warlock, naga shaman, and saurok rogue on Heroes WoW and Caustic WoW.)
