Thoughts on adding a single crit rune to auto attack based pages?

It's useless. Run 5 or 10 % or better don't.

I run two of 'em for 2% crit chance. You're only losing out of 2 AD, and a lucky crit in a trade can easily swing the lane in your favor.

It's why crit% runes need to be removed from the game. Thankfully Riot is going to be revamping Runes and Masteries this season.

Nno harm in trying

You're only paying 1 AD to play the lottery in lane. It's not that bad.

You don't give up much for an off-chance to crit early. It's worth it if you feel like taking the chance on it.

The amount of times 1 AD would win you the trade is likely less than the 1% chance to crit.

If you were to battle early game, and crit not once with a crit rune, and the enemy survives with 15 ish hp, you wouldn't even have killed him with the extra AD since it takes about 10 (even less) autos to kill someone early.

Now if you were to crit once, you would easily win that fight.

My logic is flawed because abilities have ratios, and lifesteal also applies, but it's an indicator of how irrelevant 1 AD is to how much advantage 1 crit gives.
