Why Crit is a bad design and should be deleted:
Why should Crit be deleted?
League of Legends is a competitive game where decision making and what you're going to do to win the game, the trade, the teamfight, etc. is a big part. What crit does it introduces RNG into a game which should be decisive and knowing your strengths and weaknesses of your champion to win a trade. With this RNG factor it allows RNG to win a trade that should have been won by the opponent, which isn't really what the game should be about. One lucky critical strike could possibly when a game depending on time and where you are. These are pretty much the reasons why you guys, Riot, removed a lot of the RNG from the game. Such as the slow on Phage and various of other things that I cannot remember off the top of my head.
What can replace Crit?
I was thinking about this, what can replace it? Well I've came to a conclusion what can replace it. Items which strengths your autos by a %. Like PD can make your Autos more powerful and give Atk Spd, and then another item can give less atk spd but strengthen your autos even more than PD. The items can be like gold gain items, you can only have one. Though it's just a rough idea, could be worked on a bit. Think of like an AD version of Nashor's Tooth but a bigger bonus.
