An idea for a kalista rework?

Passive: Martial poise Rend Kalista's basic attacks lodge a spear in her target for up to 4 seconds, stacking up to 254 times and dealing xx+0.0xAD as bonus physical damage as an on-hit effect that can also critically strike.

Q: Pierce ACTIVE: Kalista hurls a fast and narrow spear, dealing physical damage to the first enemy hit and applying on hit effects. Additionally If Kalista enters a movement command while winding Pierce, she dashes a short distance in the target direction, scaling with her boots tier. PHYSICAL DAMAGE: 50/80/110/140/170 (+ 100% total AD) Cooldown: 3/2.75/2.5/2.25/2 seconds

W: No changes

E: Rip/vengeance (this is essentially the same thing minus the reset) Rip: Kalista rips all lodged spears from nearby enemies, dealing physical damage and slowing them for 2 seconds, with spears beyond the first dealing reduced damage and afflicting enemies with "Vengence" for the duration of combat.

Vengeance: Rend spears no longer lodge in enemies, and instead grant kalista 20/25/30/35/40 movement speed for one second.

R: No changes

Thoughts?
