@Riot, Kalista's really weak; what are your plans with her?

She's sitting at a dismal 43.9% at high elo; and even her most experienced players are not coming close within 3% of a 50% winrate; all while sitting at a dismal 1.16% pickrate. You have a higher chance of seeing Twitch Jungle, Rengar Top, Zilean mid, in Plat +, than you have of seeing Kalista ADC. All while outputting the lowest damage per game; and having the worst synergy with crit items.

I recall you guys saying that "Just as other marksfolk align with cooldown reduction or critical strike chance as a core stat, we're pushing Kalista to embrace attack speed as her primary scaling given her stand-out strengths as a bunny-hopping battle-banshee", if that's the case; why does she have such mediocre base attack speed? She scales very poorly with Attack Speed Items as a result; so I have no idea why she has such a horrible base attack speed. Attack Speed per level while near your support, (or tank if Jungle Kalista) is completely useless once that person dies.

I seriously don't understand why people think her dashes are the problem. She can't cancel her auto attack animation so no matter what she's doing (chasing or kiting), she's committing to an action (where as Lucian or Ezreal can cancel their auto and reposition with E; or Vayne with her Q; Tristana with her W).

I also don't understand why she should lose so much DPS when slowed; sure I can get a Nasus Wither or Randuin's; but should Lulu Glitterlance, or Bard empowered auto attack cut her DPS in half?
