Hexakill TT
So, honestly I think this gamemode got the worst feedback of any other mode. I know I may get hate for this but hexakill was probably one of the worst ideas to come to league. Adding one player really doesn't do much. Twisted treeline is also way too cramped for 6 players in my opinion. And honestly its whoever has the better team fight burst wins. Its pretty much decided in champ select. The better the wombo, the better you snowball into an impossible ball of damage.
If rito is running out of ideas they should listen to the community because they have great ideas. The original Hexakill on Summoners rift was also awful so I dont see how just putting it onto Twisted treeline makes it better. If you do this why not just put the gamemode on all maps... At this rate hexakill could be that bad and still be about the same if that makes sense.
