So first I got all furor runes(crit dmg) and quints of desolation(armor pen). Recently I ran into a couple dodgy mofos and decided to switch out my yellows for evasion and it's really amusing to see a nice DODGE pop up. And now I'm considering replacing my blues for either more armor pen if its possible, or crit chance.
Just wondering what other master yi players do with their runebook. Also what do you guys think is more important for master yi, crit chance, crit dmg, armor pen, flat dmg... anything else?! Is dodge pointless on yi?
