Stop mana gating Lux and gut the f*ck out of Ekko.
So I decided to start learning Lux after a good couple of experiences with her in ARAM games.
My Summoners Rift game as her in a very long time coincided with my first experience actually laning against an Ekko and I have to say that despite him having mana and (laughable) mana costs, laning against an Ekko is more frustrating than Release Rengar because at least his leap is a dash and you could simply try to avoid brush. But Ekko gets a Dash that allows him to get into range for his blink. Not to mention he gets a shield on his W that make's Lux's look like a joke and a stun to boot. He might as well have Ranged auto attacks too.
Meanwhile Lux's E has a mana cost greater than her ULTIMATE and Ekko's is still QUITE LITERALLY FREE.
