Making champs have a greater weakness while making their strengths over bearing to deal with for some champs is making the game less enjoyable.
I remember Irelia use to have no truly bad matchups. Sure there was Wukong and Panthon along with a few others that were a headache to deal with but if you took extra armor runes and played like a bitch for the first 7 to 10 minutes against Wukong and Panth you could usually brake even or win and it felt rewarding.
But the game is constantly pushing counter picking over skill matchups. Riven E nerf and Q buff made her good matchups better and her bad matchups worse being a prime example of how this works out.
