As opposed to even giving her a QoL buff, they ninja-nerfed her this patch with the recent change to Auto Attack Lock- In; you now have to enter your move command within the first half of the auto attack windup or you won't get the dash off, and you'll shamble extremely awkwardly off. This effected her last hard core mains and you should probably report every Kalista in your games unless they're scripting and then you'll report them anyways.
Now this would be fine and dandy, and maybe perhaps understandable if Riot would patch this bug. Unfortunately, Riot has been very indecisive with Kalista's bugs; such as E auto double casting bug (therefore you lose the reset) which has been around since release, or how the patch 5.22 notes on that Kalista's dash speed are incorrect; now only scales with movement speed as opposed to attack speed, or the shift click bug that's been around since 5.6 that reduces her attack speed when using shift click. All 3 of these bugs haven't been remotely fixed or addressed or even acknowledged.
Next year, expect for some nerfs to Hurricane (her core item), buffs to her hard counters (Draven, Tristana) and nerfs to the champion she counters (Sivir, Ezreal)
