So uhh, the reason why Xenos could kick our butts at the start is because he's a genetic supersolider monstrosity that is being enhanced by an artificial version of the same echo that makes US the main character.

I don't know how you felt Heavensward was 'big'. I feel the presentation was similarly lackluster but acceptable, I think your tastes and willingness to consume media of middling quality has lessened and you think the story overall worse because of it.
