All of them except human.
Humans are too “generic”. And I have slain many of them.
Draenei (LF included) and Dwarves (DI included) paladins are eons ahead imo. Closely followed by Zandalari Troll.
Blood elf and Tauren are alright I suppose. Not my pick though.
On top of this Blood Elves and Humans could use an updated Charger model. (not counting the legion order hall mount)
