If we keep this preseason length, we have 4-6 months preseason in 1 year. It could be that one actual season will be shorter than the preseason.

On the other hand it takes a lot of time for them to implement "feedback ideas". Those ideas though usually get implemented within a season and not at the start, which makes you wonder about the purpose of the preseason. And then every few patches they suprise you with some changes nobody asked for, like the removal of the all previous feast maps.

Preseason is good to learn the changes, but it fails to get desired changes quickly enough for the next season. Therefor it could be shorter, if changes aren't made more quickly in the future.
