New gamemode?

I think this post belongs in here. Well um I was wondering if there was any talk of a new game mode coming out? Like how there was once that game type where each team was comprised of only 1 champion. Oh and poro king lol. A lot of fun. Wouldn't it be cool to have a separate playlist that where we could play all those things? Yeah, just putting my ideas out there.

Also since I'm fairly new to league, anyone mind telling me some of the other game types that have been out? I'm curious.

Thanks
