So, I play twisted treeline simply for fun with my friends, because it is easier to get a full team. After a long time without any updates, can we expect either a new 3s map or an upgrade to TT coming anytime soon? I think that you have been been producing champions at a fast enough rate, possibly too fast, as Zyra, Diana, and Syndra seem to share art. Perhaps it is time to switch gears, and add new content in a different sector of the game. Overall, I would much prefer a new map over new champs, as that would completely revitalize the game.

This thread from General Discussion may be of interest to you.
