Petition to make non-map based rotating gamemodes on all maps.

When you go into a custom and try to make a hexakill you can only do it on twisted treeline. (What if I wana take baron with 12 level 18 junglers with 2 nunu players?) U.R.F. : (Not sure if it can be on other maps, don't remember when I checked.) If and when they come back make Black Market Brawlers and Doom Bots available on all maps

Am I missing any game modes?
