On one hand, everyone that wasn't there misses the story (which let's be honest was hideously bad but Anet learned loads from the feedback). Tbh I would only want to see Marionette returned because it was an okay fight that set the foundations for things like silver wastes and dragons stand. I do feel like the ls1 movie could be a bit more detailed. But in all honesty there isn't much that I'd like to see returned. Just my honest opinion
