How to rebalance Lucian
With the recent changes to Lucian's E I think Riot has strayed away from Lucian's Matrix style gameplay where he is trigger happy but just out of harms reach if played correctly. Adding the mana cost to the E was a good choice in the early game because he can dodge skill shots too easily which is currently the meta for support IMO. I have thought of a way to change his E a little bit so he is a rewarded in teamfights for good focus.
Relentless Pursuit : If Lucian hits enemy champions with two of his passive double shots, his E is instantly reset. Lucian's basic auto attacks will no longer reduce the cooldown of his E.
Example : Q AA W AA CD Reset
