Basically every faction leader on the Alliance is a better leader / potential king than Anduin is. But we have him and I fear we’re stuck with him for a long time.
Honestly I really wish Alliance and Horde would swap roles, we could need someone a bit more like Sylvanas and Horde could need someone a bit more like Anduin. But with both around this won’t happen, Sylvanas and Anduin are dragging both factions down.
