I really don't think he's elezen either, all his "elfish" features are really the padjali ones + as Enkidoh said being "a little" dead doesn't help.

But returning to the OP, if they made them a playable race I'd probably throws tomatoes at them. The lore already makes you feel wrong and incredibly unique for being a white mage without being a padjal, and you see a load of white mage players around you, in game...can you imagine the same with the race?
