True Cost of Crit

Currently the cost efficiency of Crit is calculated based off of Brawler's Glove. However, seeing as the damage that Crit does is based solely off of AD and crit damage multipliers, it would make more sense to say the value of crit is a function of AD. Seeing as 1% crit chance increases your average AA dps by 1%, I will be using 1% crit = 1% AD, (1.5% AD with an IE).

So someone for someone with 300 AD with an IE, the value of the IE would be 65 AD35 G/AD + 0.2 Crit prob * 1.5 crit damage * 300AD35G/AD = 5425 Gold.

There are some problems with this method. For one, crits are not guaranteed for values below 100%, making it hit or miss, and thus unreliable. However, the value of the "burst" damage from crits should be more than enough to make up for this. Another is that crits only scale mostly with AA's and not overall physical damage. This should be minimized though because most champions that build crit do most of their damage though AA's.

There is a problem with your calculations. 1% crit is equal to a 1% increase in DPS, that is correct; however, DPS is a multiple of AD, AS, and armor pen.

However, the core of the argument, or at least the argument I think you are making, remains the same. Crit is a multiplier of damage and item efficiency. However, like any multiplier it requires a large base value to create large results. That is why ADCs are/were unimpactful before their 2/3 item core (season 4 - ie, ss/pd, lw; season 5 er/ie, some zeal item, LDR/MR).

There is nothing wrong with crit's efficiency. It isn't good (i.e. reliable) unless stacked on a glass cannon carry, and, outside of a few niche cases, it's the only way to kill tanks or bruisers in a reasonable time.

The cost of crit? Dignity and respect.

Applying the same logic to other stats gets really messy, really fast.

Firstly, it's not like all the other stats don't work that way as well. Health's value is "multiplied" by armor, likewise, armor value is "multiplied" by health, attack speed "multiplies" attack damage, and so on.

You're also mistaken, as Sehlikah pointed out before I could get in here, DPS is made up of multiple factors such as AD, AS, and armor pen. Further, you are overlooking the matter that champion's have Base AD which varies from champion to champion.

But basically crit's cost efficiency value calculation is fine; it wasn't ever anything more than a rough guess and was only suitable for comparing a few items anyway.

There is a difference between cost efficiency and value.
