Doesn't make sense for a mask user to gain the other racial abilities. If they do need to still gain them, they should be heavily penalized, like 1/3rd the benefit and double the cooldown compared to when used by a real person of that race.

Having all the racial dialogue as well strikes me as nonsensical too, why should someone donning a shapeshifting mask suddenly gain actual cultural/historical knowledge of the race they are copying? They should actually get into trouble for trying to pass off as another race and then acting/saying the wrong things.
