Unpopular opinion, you should be required to maintain a 50% wr to stay in your elo (plat+)
If you're in an "above average elo" your winrate should reflect that. \If you're in an elo and not doing well, yes loss streaks happen but im talking about CONSISTENTLY under 50% wr in a span of weeks. You should demote, or have the warning trigger of demoting if it doesn't get fixed. There's simply no reason to have a negative win rate in plat+. (We can even make it diamond+ if you want) There's absolutely no justification of "i don't consistently win HALF my games but im in above average elo" It simply doesn't make any sense for that. It doesn't really apply to lower elos because there's nothing reflected through win rate there. Just baffles me being in games with diamonds and they have a 48% wr in diamond in a span of 500 games or more.
