@Meddler: Potential balance suggestion for Orn to make him not auto-win the late-game.
Because let's face it, Orn isn't the ONLY late game champion, so it's not really fair that he gets to auto-win because he buffs 5 players.
These guys needs to stand a chance, because by design, late-game belongs to them too:
etc
Allow the enemy team to make use of his passive for 2x or 3x the cost. So if they manage to stall out a game and turtle, they don't remain at a permanent gold disadvantage. (And if a 5 man Orn-buffed team fully equipped with 6 items allows this to happen - they kinda deserve it?)
Potential argument against: "But ally champs shouldn't be able to help the enemy team."
Pretty sure we're long past the days where that statement is a true one. All of these guys can help the enemy team a lot easier than Orn can (and it doesn't even need to be intentional):
