Orbital Strike Lucian: Engage

I don't want to drum up the war drums or anything. But it has really kind of hurt me watching the fall of Lucian, more specifically was the notion that these changes were aimed at giving Lucian meaningful weaknesses, notable strengths as well as a distinct identity.

Lucian has had his AA range reduced, Functionality of Dash changed, losing slow-removable and increased CD, introducing a mana cost Ardent Blaze has had its damage completely removed in place of movement speed Lucian's Ult has recently had its CD increased

What niche does Lucian fulfill that isn't better done by Sivir? Sivir is safer has better wave clear, a AS steroid and even long range poke. I feel like while lot of Lucian's identity has been defined over these iterations - Lucian's uniqueness has been diminished as a result to this wave of nerfs. I think Lucian should be a smooth gunslinger type marksmen JUST outside of arms reach but its starting to seem the risk isn't worth the reward anymore.

TLDR; While I feel like some of these changes were welcomed, I don't want Lucian to follow a path similiar to Cassiopeia or Skarner.
