Why are crits in the game instead of an increase to sustained damage?
Getting rid of RNG is something riot strives for. We saw the 4% increase to crit chance mastery being removed to prevent early game lanes from swinging because of one lucky crit.
I like crits and find them fun, but at a competitive level I don't see why they remain in the game. Infinity edge has only a 25% crit chance, and if a marksman gets two lucky crits in a row on that thing, they might win an engagement/duel that they might not have otherwise.
What do crits add to the game? And why have this RNG in there instead of a linear increase in damage output?
