Problem was, the changes accidentally never went out. So after it seems like a champion was overnerfed and is trash now, we have to wait a little to make sure that's actually what happened. Remember also that Hecarim was considered weak for the longest time and has skyrocketed to the top of jungle picks now with no changes.
Well in Hecarim's case is because other junglers were nerfed, season changes, item changes, etc
You don't have to buff a champ to make him stronger you can just nerf everyone else around him, like how bot lane balance was for the longest time in season 2
