I think it's a mistake to for them to get into the weeds of the story in their trailers, for anyone who hasn't been paying attention it probably means next to nothing to them. Oh no! Gortash knows Ketheric Thorm! Who? And again, Who?
They should be harping on the spectacle of the city, maybe with some nostalgia beats, and showing off the classes and encounters more. The Nautiloid sequence and the tadpole are enough of a hook. Maybe this is a result of such an extended EA process they're afraid of repeating things.
