there are people complaining no matter what riot does so how about....
...Riot would rework the Twisted Treeline map into something that everyone could enjoy.
I mean aside from it's small community that it would be an actual competitive map which would even appeal to Esports. This way we'd have a map for fast paced actions, short games and more solo carry potential and one map for the longer games (30-50mins) for the part of the community who prefers longer games which are more teambased.
What I think about is that the TT takes some of SRs strengths like the towers which are closer to each other the closer you get to the nexus or the jungle creeps. Also It'd have different items which are cheaper so you can get powerspikes earlier. EG the same as Crit Adcs are at the moment on SR.
OFC not everyone would be happy about it here will never be the time when everyone is satisfied, but i think most players would then have their preffered environment to play in.
Much love
(sry for bad english :P)
