I keep seeing people making this mistake aboutallied races when they make suggestions about potential allied races.
Guys and girls, allied races are not supposed to be completely new races. They are actually offshoots of a race that is currently playable (they're actually just sub-races) meaning that while some of the races in the game are using the same animation skeleton, like the vulpera using goblin skeletons, they are not exactly a subrace for a race that is currently playable.
So i dont think that vrykuls, naga, ethereals, etc are gonna be possible future allied races. Instead we should be talking about potential candidates which are part of a currently playable race. Like wildhammer dwarves, taunka, felwood worgen, the broken draenei, etc etc.
