It sucks. We waited two years for this and this is by very far my most favourite skin line. It's really sad, especially since these skins are so well-made in terms of avatars and animations, but so uninteresting and unfitting.
If we wanted Dark Stars, we'd get Dark Stars. If we wanted Anti-Star Guardians, then make a new line.
What we wanted were colourful Star Guardians and an invasion event. Just another case of Riot NOT LISTENING TO US.
