Level scaling for pokemon breeders has been brought to attention to the devs and might consider implementing it.can we get a second breeder to train with, with Higher levels because the leveling becomes quite Annoying with him with his level 20, maybe 1 on level 40 at the 3 or 4 gym (if the update includes the 4 gym) would be nice.
As for the next update, it'll probably not be including a new gym and focus more on map details and character development.
