Tyrande wasn’t even at the Broken shore for the assault on the Tomb , her Orders most holy site after abandoning her husband in val’sharah to defend her goddesses lands.
And you know why? Blizzard wrote her in for 7.2, but changed it completely to make it more legion based against the Class Order halls instead - never even tried to release what they had done as an alongside story.
I also hear Suramar 7.1 was actually initially done by Vereesa for the alliance, but changed last minute almost as if they forgot their own lore.
While it is possible we shall see more of Azshara and those two won’t get involved till much later and the final demise of her if it is t 8.2, I wouldn’t hold my breadth.
I maintain blizzard giving the horde nightbelves is the only thing keeping the race relevant. Darkshore was token fan service, they already said we get KAlimdor, though I am suspecting they change their mind
