They shouldn't have added so many gyms in big cities like mine. Rural areas needed more gyms and pokestops.
My city now has people no longer stressing over occupying territory. They already have enough gyms to split among themselves, why should they fight over them? This, coupled with the lack of incentive to attack due to recent changes and coin reduction, has made receiving your mons back near impossible. Even worse, people just won't stop feeding them! Your own team can be keeping them hostage, exactly as I feared.
They should have made it so that you can only feed berries for 1 day and then when motivation hits 0 the mon returns or at least can be recalled by the owner.
