listen dude its not like blizzard are gonna have actually paid any attention to this idea. i can 100% promise u it was broken before ysera died and when this fact is told to us you will be like "well OBVIOUSLY elune saved ysera from the maw, i knew it all along from the valsharah cutscene"
but ysera wont even be the only character they overlooked with this terrible idea.
as usual all effort put into speculation by applying the lore's own rules to the world is entirely wasted.
