I'm sure Gamefreak is shitting their pants looking at these user scores (inb4 shills).
Assuming Gen 8 comes out in precisely 1 year, what could they feasibly fix in time to address these complaints?

Do they have time to revamp enemy trainer teams?
Do they have time to re-do level design?
Implement a hard mode?
Integrate a fully fleshed out Battle Tower?
Redo the story?

How much time is a year when it comes to video game development?
