Idea for Kalista change

So an idea popped to my head, I'm sure I'm not the first one but Kalista was nerfed continuosly because she was kiting everyone and being too powerful in general and now she's one of the worst.

What if we switched the passive and W around? Not sure if the ghost scout should stay or not or how to put it in the passive, but if the problem was continuous kiting, make W give you like 5 seconds (can be less or more) of jumping time with AA's and Q, then put it on whatever cooldown would work. Maybe leveling it up would give less cd or some other bonus during the active time, or passive attack speed.

The jumping on basic attacks can't quite be removed or Kalista would lose her identity but making it an active steroid would mean that there's downtime to engage on her.

I'm not Kalista main or anything, played her in normals few times and couple of times in ARAM so I don't know all the ins and outs of the champ but there is a reason she's not played that much.
