Suggestion for a couple Kalista buffs/changes

Goal: Give Kalista a bit of up-front duel power so she can trade better in-lane with other marksmen who have a lot of harass.

Suggestions: Passive:

• Picking up a missed spear gives her next autoattack within 5 seconds double leap range.

Change her Q into a rapid-fire barrage of bolts that each stack on the enemy and deal damage. Pierce: Kalista winds up for double her current attack speed wind-up time, and launches 3 spears very quickly in the target location. The first spear deals 10/30/50/70/90 true damage. The second spear deals 10/40/70/100/130 (+70% bonus AD) physical damage. The third spear deals 10/40/70/100/130 (+70% bonus AD) magic damage. Each spear will trigger Rend and Martial Poise (if queued). Will pierce through all targets within 400 range and stop at the first target outside of this range. Travel Speed: 2400 Cast Time: 3 spears are hurled in (attack timer * 1.5/1.4/1.3/1.2/1.1) seconds. (Kalista is locked in place for the cast time).

Increase her Q damage a bit early so she can harass more easily. Damage: 60/105/150/195/240 (+80/85/90/95/100% AD)

Hurls a spear in a direction dealing 30/50/70/90/110 (+50% AD) physical damage. The cooldown is reset on champion hit and deals 5/10/15/20/25 (+15% AD) bonus true damage per champion spear hit (stacks within a 4 second window). Mana cost: 30/35/40/45/50 Cooldown: 12/11.5/11/10.5/10 seconds

These might all be shit, it's fine I'm just putting my thoughts out there.
