46% crit dmg runes question

It makes anything considered a critical hit do 46% more damage, same as IE makes it do 50% more damage. For a total of 296% damage on a crit, instead of the base 200% without IE+CD runes.

yes. however. don't get those crit runes. the difference between them and getting just regular ad runes and defensive. does not exist until you get a decent amount of ad and critical chance. the thing is. if you don't crit. they are uselss. means your early game is pure garbage.

don't take them. unless your in low elo because they can work there people don't punish you.

You will need extreme training in early levels if you take those. You won't have some tankyness or AD to CS as well as the other ADC.

Late game will be a different story.
