Cute first mission! It feels super basic and simple, but that's not necessarily a bad thing. The story kinda mirrors the original with Maiev and Illidan, so I'm not sure if it's meant to be a different reality from the original campaign or what.
The ending was a bit underwhelming, to say the least. That cinematic with Lilith dying felt pretty disappointing—there should've been a proper boss fight instead of her just going out like that.
On the bright side, I liked the extra quests and the mini-boss, but honestly, he needs more mana to use his spells more. Also, having more secret spots where Lilith can use her blink ability to reach them would be cool, similar to the og campaign.
Overall, it's a cute and simple first mission! Here's my playthrough:
