Nostalrius Begins - Quality wow vanilla realm (1.12)

Been sittin for a couple of hours, trying to complete a quest involving Tyrande Whisperwind (Boss in Darnassus)

If she ain't bugged or something, horde has killed her. Anyone know respawn timer, of her and the other faction bosses?

/Amanday, 45 warrior

As I recall, Tyrande was the easiest Faction leader to kill due to her HP and Location, so they increased her spawn because she was farmed.
