Mosh pit Gamemode

I think Riot should should look into creating a Mosh pit game mode feature to replace the Rotating game mode. This would spice up the game a little bit by randomizing what game mode you get every time you go to that feature. So for example one game I would have Ascension, then the next game I might get All for one, etc.

This way Riot doesn't have to focus on figuring out a schedule for modes, all that had to do was add a randomize feature to their code. If they wanted to feature a new game mode, they could take out the mosh pit feature and showcase the new mode.

What do y'all think? Is this possible or has this been talked about before?
