Riot wanted to turn Cass into a poison mage,

Riot: "So we're going to rework you, Cassiopeia." shudders Riot: "Don't worry, it'll be painless and you will be better." mistrusts Riot: "No, seriously. Notice how we wanted to make you a poison mage, but instead you're just an E-spam machine?" "Yes..." Riot:" Well, we're going to reinforce your identity as a poison mage. Wouldn't you like that?" :" Well.. a poison mage is kind of a cool identity... so... I guess I'd like that... :) " Riot: proceeds to make her poison dmg trivial and reinforce 10x the E-spam playstyle : "But... but you said... I'd... poison mage... what... what is this... I broke an E key again..." Riot: "Well, you're a good pick now. Enjoy! Oh, by the way, we also took out your lore and gave you 2 sentences of generic Shurima stuff, because we're super into Shurima now, and we gotta have champions coming out of there. You're. Welcome." : "Riot... you promised!"
