Koreans build this literally every game, and I NEVER see an LCS game where he doesn't build this. And literally EVERYONE gets manaflow band too, so please don't even try to tell me this item is not mandatory on Ezreal. Can someone plz explain to me why Ezreal's mana costs need to be so damn high? He has enough counterplay in his kit. There isn't a single ability in his kit that can't be dodged or avoided. And he doesn't abuse crit like other adc's.
