I have a had a idea much like this. It is a good one, but more details would help it sound more viable. Like, you could use the ball as a weapon if you chucked it at an enemy, dealing a little damage and stunning briefly, but running the risk of them getting the ball. Also, there should be a map (maybe the same one as this!) with a third team made of jungle type enemies that mess around with the players, and instead of a nexus, they could have baron or Vileman (or whoever the spider guy on TT is) as there leader, and if they are killed, that team goes away and a turret or something is given to the team that killed them, as well as a huge buff.
Also, having the ball should silence and/or blind you, especially if you could use the ball as a weapon.
Also, I feel these two would be OP on this level.
