Please Riot, allow to play any gamemode on any map with the matchmaking.

I don't think matchmaking should allow to play a gamemode on only one map. For example, Hexakill is available only in Twisted Treeline with the matchmaking, if we want to play it on Summoner's Rift, we have to do it with a custom game and finding players for this can be very long. Can you please allow us to play any gamemode on any map with matchmaking? Also let us play gamemodes against bots and add permanently Butcher's Bridge as an ARAM map please.
