And who else is left? Blizzard will never turn Jaina, Genn, Anduin or other fan-favorites into villains. They just don't have balls for that. But clearly, Blizzard writers don't care about Turalyon at all. In Legion Turalyon's sole purpose was to show how badass Illidan is, and since then he is often portrayed as a joke, a far cry from his book characterization, if you ask me.
