How to fix Kalista

Probably it has been proposed a thousand times already, but I do not believe that Kalista does not have a place in the game. I am actually kind of sad by the state of balance at the moment where we have champions that sit in the low 40% of win rate.

Anyway without further ado, we all know that the biggest problem for her is her passive, but I believe there is an easy fix:

Kalista's Jump distance and speed are affected by slows, this means that with 30% slow you would jump 30% slower a 30% shorter distance . This would make the passive much more manageable and not a hard counter to any melee without a gapcloser (You can still attack normally by standing still).

Also: give her the Mordekaiser treatment with a shitty base attack speed but unnerf her other abilities and add more punch to them since now attack speed and endless kiting would be much more difficult to obtain. E damage (by quite a bit) and Q damage UP.

How does that sound?
