It's less of a hassle to go back to a PC every once in a while and tailor your team for beating a specific boss trainer than figuring out how to make the most efficient static 1/2/3/4/5/6-monster team for beating the entire game with. Also the added benefit of getting to use a larger portion of the dex per playthrough.
