As to the OPs point, I honestly have no idea how to feel about the Night Warrior. Most of my impressions of the character is surface trait. Like, I like the general lore they’re building off the concept, and that new model looks real good on Tyrande. That extra tone and muscle really fits her.
However, she already was pretty damned powerful (at least comparably to any Horde character) that giving her a powerup feels more like just respeccing her to a Melee-Priest. Not to mention … i cannot fathom a reason to put off Nate’s death till the prepatch, if that’s all they were going to do with him? I also have rather … strong opinions about such a favorites playing “One True God”.
