@GFX47 yes. But if you're improving and tere's a guy that's rocketing up, who demotes you, you'll have only one guy to overtake to be promoted again. And that guy who beat you, deserves it.
As for someone becoming inactive and getting demoted, why not? Your ELO doesn't change
. It still shows that combination of your dedication and competence.
Are you saying that people should just become inactive after getting to Grandmaster in order to keep their title? Hell, no! If there are people getting 1-2 points for a victory and losing 20 for a defeat, they need an awesome win rate to keep that up. And deserve NOT to be put in the same group with less skilled or lazy players.
@pier4r League names are just for show. Matchmaking can still happen cross-league, depending on your ELO. It won't be much "better", but it will give players with competitiveness in mind a reason to play.
Related story: I didn't know that I hit Grandmaster before seeing that there's a guy who only had victories against me in my match history (T-800). He had ~75% win rate at the time. I was rank 16. I haven't played since because I'm too lazy to move and connect those boxes (even though I know what kind of improvements I should make). As other people gained ELO, they got above me and now I'm 23rd. Haven't played a single match since, because I don't want to lose with an AI I know could be better. Such players don't deserve being in Grandmaster league.
