Sub-Races are a fun idea I think. Easy work around to adding new races but not really. You get some of the hype in there which is the important bit.Could be:Sylvari ->Soundless Sylvari (More pale tones, perhaps some older looking hair styles, new racials)Charr ->Flame Legion Charr(New body types, new faces, new racials)Norn -> Not too many lore-based choices I can think of. Maybe something to do with spirit of the wild infused Norn.Humans->Canthan humans? Awoken undead? A lot of choices hereAsura -> Inquest Asuran? Not sure what would change physically here. The most important thing about new races is they add hype and a new starting point for players that want to join.If a new race is off the table completely I think this is a pretty good middle ground.
