There is something to be said about being autistically devoted to keeping the timeline stable. Once you start meddling, you never have a reason to stop. Every leader will be in your chambers begging you to go back and strangle their rivals in their cribs.

I can understand the logic, even if it probably could have worked out regardless you don't want to risk it or open that can of worms.

That's why Blizzard just recently wrote an entire quest to send you back in time and prevent Alexstraza from escaping early. You need her to spend a couple more years getting gang raped and harvested for babies to protect the timeline. And then go talk to her about it after you finish the quest.

That totally wasn't a fetish for someone in the company. Totally.
