Twisted Treeline was a permanent 3v3 mode with ranked and draft.
It was deleted in 2019. Some players had a lot of fun and wish to bring it back. Can be chilling at night with with a small group of two other friends or trying hard to rank up!

Arguments for players :
-Shorter games
-More straight forward team comps and satisfying teamfights
-Easier to get a team of friends to get along and play with
-Less fog of war + smaller map, enemies are closer (and allies too!) - get help and less cheese!
-Less farm more fight
-> all of this made this gamemode less frustrating, and enjoyable

-Diversity - a mode that was always available (not temporary like Urf) and had a different atmosphere
-Still a serious mode, could be played ranked or draft.

Arguments for Riot games :
-Already coded
-Can always monetize it with customizable effects/towers...
-Would bring back some old players
-Always brings some new players to the game, who will play main modes too
-Keep it as it is, no need for a rework
-Listen to the community, make us happy ✧( •̀ ω •́ )~[]

Objective : as many summoners as possible voicing their will to play 3v3, so Riot Games enable the gamemode again! :D
