>>54030535Set ranked points depending on your rank. For example, Pokeball League had +20 on win and -10 on loss. But Great Ball League has +20 on win and -20 on loss.
You can not rank down to another League but you can rank down within the League you're at.
You do de-rank at the end of the season, and the amount of deranking depends on the Pokemon tier you're at.
