why we have crit imo
allot of people complain about having crit and how its rng. I think riot wont remove it because it would cause massive massive game balance issues. as an adc main without crit adcs would become almost useless against a tank heavy team (since the only way you can burn threw a tank is armour pen combined with crit) and no were near as strong as a apc (ap carry). so Riot would either have to buff adcs/ad items or nerf apc/tanks/apc and tank items. that would be a huge job so i think they would rather leave crit in then try and take it out and then rebalance the game.
