What bothers you? The fact that they changed league tier and still being listed as your opponents in league? What do you think is wrong with it? Still same player doing same stuff like you do.
If you want him to be removed from your list then who should be included in it? If system decreases pool of opponents only to ones with same league tier as yours with around the same rating and activity do you REALLY think it will be more easier? As long as we receive biggest possible pool of players with as much as possible same activity it becomes more balanced.
If only FTX could add some sorting with the player levels it would be even more balanced
But if you start building walls it becomes only harder
