New Game mode
Is there any chance at all that we could get a permanent PvP game mode like Ascension? All we have right now is ARAM (where you can't choose who you want to play) and Twisted Treeline, which gets boring after a few games. Either that or could Twisted Treeline get a rework so that it's faster and less snowbally? Outside of rotating queue, there are no options for a game mode with just straight up fighting, without having to farm minions, while being able to choose who you want to play.
Also, I think such a PvP oriented game mode would help a lot when it comes to experimenting with champions and build-pathing opportunities. Both SR and TT are too slow for this sort of thing.
