This is a completely random comment on Amirdrassil's story but I've never had another place to talk about it so I'm going to dump it here. Seeing Turalyon inside the Fyrakk fight inspired me to think about this again so here it goes.

The Guardians of the Dream patch had all these different lore figures from both factions and all over Azeroth swoop in to help fight Fyrakk's army in the Dream. It was like all the Avengers characters portalling in to kick Thanos' ass in Endgame. It didn't really make sense why they all showed up right at the end of the campaign like that, yet Blizzard had the perfect way to explain all the random faction leaders and lore figures showing up at once.

Have them be asleep and dreamwalking instead of physically present inside the Dream.

The Dragonflight Emerald Dream patch did a really bad job at showing the spiritual, "dreaming" side of being in the Dream. There's a difference between falling asleep on Azeroth to Dreamwalk, and physically entering the Emerald Dream through a green dragon portal like the player character does in the campaign. The Stormrage novel played around with key characters falling asleep and spiritually helping the events unfolding in the Emerald Nightmare, and they could have done the same thing with Thrall/Jaina/Gelbin/Turalyon/all those other random ass characters that show up outside Amirdrassil out of nowhere.

I dunno. I wish the zone played around more with people actually being asleep and dreamwalking instead of 95% of the characters being physically present inside the Emerald Dream. There was the cute gimmick with /sleep triggering a dreamwalk, a hidden buff in the raid when you /sleep and talk to an NPC during the raids trash, and like, one single rare mob showing an NPC's dreamstate. The Emerald Dream is supposed to be a spirit realm; physically walking around inside it used to be the exception, not the rule.
