Lucian is terribad. There are only 2 good things about him:
- long range dash
- good AA animation
Everything else about him has been guttered.
To fix: first, we establish Lucian's identity as a very mobile, short ranged, bursty lane bully that weaves spells and autos, who moves fluidly during teamfights and who needs to dive into fights to get the most of his kit. This gives him a unique identity different than other lane bullies such as Corki and Graves who are either more about long range poke (Corki) or more autoattack based (Graves).
Changes: revert nerf on his passive. Reduce mana cost of Q. Reduce CD on his W. Finally: Reduce E cooldown and his E tenacity, scaling with his movement speed. For example:
Relentless Pursuit. CD: 16/15/14/13/12. Dashes in a direction. The cooldown of this skill is reduced by 2 seconds per basic attack performed with Lightslinger. Grants Tenacity (10/15/20/25/30%)(+1% per 5 bonus movement speed) for 3 seconds afterwards.
He is not very relentless when his range is so short that he gets CC'ed and killed every time he tries to fight. Why not boost his image as a relentless zombie hunter by giving him something that no other ADC has: tenacity?
