ATLEAST for the upcoming Mordekaiser rework.
Twisted Treeline has be heavily ignored by all of Riot as they continue working on things like Nexus Blitz, Extraction, URF changes and etc.
Please take a moment to revisit Twisted Treeline, and possibly make it a different gamemode other then funnel flex.
There's so many ideas that can come of a 3v3 map, it's supposed to be the one gamemode quicker and more simple than Summoner's Rift.
So please, give the Shadow Isles what it needs, fix Twisted Treeline. Stop letting it be a broken gamemode.
