By the way I have no problem with Tyrande and Malfurion saving one another. The issue is packaging 8.1 as some Tyrande story and then have her big shining moment be getting permastunned by a single Val'kyr, about to be killed by Nathanos, until Malfurion saves her.
I feel like both sides deserve their victories individually. I'd have Tyrande demonstrate the power she has now and show just how terrifying it is - then later have her be able to complete said form making it even more of a threat to the Horde.
