>>38296371I don't know how it can be "underwhelming", it's not something like Castform or Wobbuffet where it's a battle effect that can be objectively gauged, it's just a visual one.
The only problem with it is making spring the only available form from gen 6 onwards. If they aren't going to bring back season I really don't know why they didn't just do something like letting you get Spring in Sun, Fall in Moon, Summer in Ultra Sun, and Winter in Ultra Moon.
