It's not even that there needs to be a focus on trainers or Pokemon at all. Keeping it even and just exploring the world and keeping things fresh with new character arcs is all we need. It's why the Kalos War and AZ are so refreshing. It's interesting worldbuilding and we WANT to know more about it. Every Digimon season has new humans with their own backstories and problems. Izumi is adopted, Yamato and Takeru are estranged because of their parents' divorce, Takato just wants to draw Digimon, Ruki sees them as tools for battle. The anime needs the same philosophy because all of these things resonate with kids.
