Remove Twisted Treeline it's an awful and poor solution.
/dev: State of Modes
... "So at the end of this season, we will be retiring Twisted Treeline. Like Dominion before it, we’re sad to see a longtime part of the game disappear. But we feel this is the best decision for League, as it lets us keep our focus on our larger game modes..." oh god, this is a kick on the balls for the community/playerbase. So, i think it's the perfect timing to bump this [it's not my own]: https://boards.na.leagueoflegends.com/en/c/gameplay-balance/E2ikbKET-proposal-twisted-treeline-gameplay-update-new-game-mode-more-riot-mort-meddler
hope dies last... Have a good night my friends.
