I just noticed that with horde earthen (dwarves), the horde now has 4 different playable models that can be paladins (BE, Zanda, Earthen, Tauren) vs 3 in the Alliance (Human, dwarf/DI/Earthen, dreaenei/LF), which is a bit silly given how paladin is the alliance flagship class.
Shaman, the horde flagship class on the other hand is available to 8 different playable models in the horde (counting zandalari and earthen) and 5 on the alliance.
