@Riot: If the tech were available, would you make a Champion who plays like Abathur in HotS?
Abathur's probably the most unique hero I've seen in a MOBA. He doesn't directly fight, and instead manipulates the entire battlefield to benefit his team. He can apply plenty of subtle lane pressure, shield and buff allies from anywhere on the map, and requires an entirely different mindset to play.
League presently has no Champion who comes remotely close to this, but I think adding an "Abathur" into the game could really break the mold. I assume Riot doesn't have the tech to add someone like him into the game, but if they did, would they want to?
