3v3 Game mode

So I know 3v3 used to be a thing and they got rid of it. But this is what I was thinking. Summoner's Rift is...the ONLY map other than Howling Abyss. What if You made 3v3 a mode again but you can have 4 different maps to play it on. Selecting which map to play on would somehow be part of the champ select. Maybe how like you see roles in a draft pick, you would also see which map you will be playing on. The maps could be Elemental arenas based off of the dragons.

Like the ocean drake map could have some kind of mechanic with water. Like the lanes could shift and change based off of low and high tide.

The mountain drake map could have like unwardable underground tunnels to traverse on the map like caves or something.

The inferno arena, the pathways in the jungle could slowly become impassable pools of lava slowly restricting players to certain areas and closing them in for a fight.

And then the cloud arena could have like animals, primarily thinking birds right now, in the jungle that you wouldn't farm but feed so that they can give you a look out from the sky, like a ward or something with farther range, or it moves around between 2 or 3 location on the map keeping an eye out for like 3 minutes. It could also just have like wind tunnels or something to help you move faster back out to lane to make the game a bit more fast paced.
