Crits are less random than you guys think btw. Your STATED Crit Chance is better described as your ANCHOR crit chance. If you "have" 10% Crit chance you have a Quota similar to thresh's soul drops. If you are below your crit per 10 second quota (which is equal to your crit chance divided by 10) your crit chance begins sliding up to about 15%. It also slides down if you are over to about 5%. Basically your REAL crit chance can fluxuate about one half more or less depending on how lucky you are. The exception of this is when you get 100% crit chance.

Sure RNG plays a role but not as large as you think. Crit doesn't have to be removed it needs to be explained.
