Olaf's late game is garbage

I love this champion personally I think he's in a really healthy state from early to mid game but when you reach late game, God, he's so trash his damage is laughable and just press R in a tf late game and watch yourself get blown up faster than the carry, I think Olaf should get some sort of defensive buff to his stats per level, as his damage falls off severely and you ult in a late game changing teamfight with a bruiser who has no damage no amount of hard cc and squishy as hell as soon as you ult, he just feels ridiculously useless when you get to that stage. And ofcourse Olaf is meant to fall off but even Lee is still useful late game, it feels like the game is punishing you for picking this champion because you were unable to close the game off.

Ok also I thought I would add this in because people don't seem to realize how Olaf works, I have played Olaf an insane amount of times, I am currently one of the best Olaf's in the world, best I ever got was top 100 or something not that is a big deal just justifying what I'm saying with experience
