That's the problem, though: crit chance is a stat you need to heavily invest into to make any real use of. Unlike other stats which provide reliable bonuses even when purchased in small amounts (including attack speed, which is practically useless on most champions), you can't expect a dependable damage increase based on just one crit item, even a top-tier one. Because of this, the gold value of crit can change wildly: it's worth 0 gold if you don't crit, but the total sum of your crit chance is worth 5000 gold on every crit you do land. By nature, critical strike is either worthless or far too strong for its actual value: it's an extremely binary system that's not even dependent on player input. This goes completely against Riot's current philosophy, which is to avoid binary gameplay mechanics and give full control of the game's outcome to the players.
