Soccer Mode

So with the addition of Poro King, we can confirm that Riot will make Summoners corresponding to new modes (If I can remember none else that is) so what if we took the poro mechanic and change it a bit.

As well as hitting enemies, allies can interrupt the path of the poro-ball and then they hold position until they either throw it themselves, get hit by a melee attack or die. The goal of the gamemode is to hit the turrets/nexus/inhib with the poro-ball until they die, say 3-5 hits.

Enemies can take the poro-ball by killing the holder, via abilities, hitting them with a melee (Maybe not too sure bout that) or interrupting its flight path.

Main Goal is to destroy the turrets with the poro-ball, get to the nexus and score the goal.

Thoughts? Too cruel for poro's?
