"If you just get rid of the dash mechanic from even Release Kalista, why should you play Kalista over any other ADC? You took away her mobility, so now she is just another immobile ADC. Why on earth would you pick Kalista over something like Ashe, Kog'Maw, Vayne or Twitch? Ashe, Kog'Maw, and Twitch have far safer auto attack ranges (even if only temporarily), Ashe has much better utility in the fact that her vision is global, and so is her arrow. Vayne, Kog'Maw and Twitch can shred tanks (and entire teams) far easier than Kalista can while not being dependent on an auto attack from a support with a rather slow AA animation (looking at you, Annie and Lulu) or low attack range (Braum, Blitzcrank). Vayne and Twitch also have evasive means to avoid damage through Tumble and Ambush."
What you guys don't realize is that Kalista's identity is the dashing, it was in her concept art, her design, and her central identity, unlike Malzahar's Void Shift. If you get rid of her passive, Other E stacking champions will have methods to get E stacks far easier, Tristana has Draw a Bead! and Rapid Fire, Twitch has Venom Cask, Rat-a-tat-a-tat, and Ambush. Kalista has no AS steroids, because none of her abilities would be replaced unless you want Kalista to be Aatrox in that she is just a ball of stats.
