I'm bronze and have no real idea about gameplay balance. Maybe it's a bad idea, but please read it.
I think that every single object in the game(sans wards) should have their hp doubled. I think it would be an effective counter to the current damage creep problem without fucking up much balance wise. Maybe I'm wrong, this idea popped into my mind while I was standing on my head, so it might just be stupid. Still decided to post it anyways.
