New game mode: SRDB
Summoner's rift dodgeball!
A super casual mode where you play SR as usual, but once in a while a ball spawns in the rift that can be picked up and thrown at your enemies. You better dodge that thing because when you get hit, you switch teams with whoever threw the ball at you.
^That's the basic idea. Actual implementation would have to be fleshed out more to give the winning team an incentive to use the ball (like gold, a personal stat increase, becoming the Rabbit of Caerbannog for a short time,...) --> Maybe something that can quickly shift a losing team to a winning team.
Here, take it.
Cheers
