So they gave her a kind of jump that has no cooldown, and gives her a chance to escape any melee clutches against melee champs she encounters with. But oh well, meanwhile at Riot company:
Riot: "Let's nerf 
!! Chocolate guy too much mobility even on cooldown HURDURDURDURR"
Ryntak1 voteshis is much longer range
BeatzBoyFTW1 voteshis is much longer range
He is only able to do it once, and has to activate his 2/3 other abilities just to cool the E cooldown back. All Kalista has to do is basic attack and jumps at the same time, much more stickier/runny than Lucian does. Well I never played Kalista before, just saying what's on top of my head of both their mobility mechancis.
AkumaPanda1 votesAfter playing Kalista a couple of matches, I just have a couple things to comment. Early game it should be quite easy to play against that passive seeing as there's a pretty obvious delay during her auto attack before she dashes, leaving her very vulnerable to cc since she can't cancel the auto to move. Though, as she builds attack speed, it does get quite crazy with that delay shortened and her dashes being longer (the distance increases based on boot tier). I think she's another one of those champions that seems crazy and ludicrous at first, but after a little while people will learn how to counterplay / play against her.

But...according to all butthurt players, they say chess takes skillz
Eleshakai1 votesThe difference is that Lucian's is on demand, Kalista's isn't. Kalista CAN'T animation cancel, she has to finish her autoattack to get her movement. So it creates a sort of predictive element to it. She will have her mobility at a very predictable time constantly, so you can work around it.
