What's the point with that quite lackluster story in Endwalker?

[Jandor]

It seems to be a recurring thing, so lets insert some plausible character deaths:

• Zenos in your body kills Alisaie and G'raha Tia before you can reach him.
  
  
• Alphinaud's dad dies when the trip to the Garlemald tower fails.
  
  
• Hydaelyn doesn't enchant your Azem stone. Urianger takes G'raha Tia's place, and Alphinaud takes on Meteion alone. You can summon everyone back for the finale but as you can't give them new bodies they'll fade away when the spell wears off. Every main Scion is dead.
  
  
• As Alisaie wasn't around to give Zenos a stern talking to he just slaughters his way through Sharlayan instead of making a deal. Krile, Tataru, basically every B character that was in Sharlayan at the time is killed by him to get to you.

I'll be honest, all of those would be far too much and I think the story would be worse for it. Doing one or two might be interesting if handled well, but I doubt it would majorly turn things around for people that didn't like Endwalkers story.
