Should kalista get some changes?

i personally like the way kalista is. her gameplay is quite unique to the role and is very interesting to play; however, i cannot seem to grasp as to why an adc, such as kalista, is not able to use item actives during her auto attack animation (specifically blade of the ruined king). seeing as she cannot cancel her autos she is always committed to the damage she attempts to create and will have to continuously attempt to kite back and forth between her and her enemy, which is good, very nice kit, but isnt it detrimental to the role of being an adc if you cannot utilize the items that you purchased due to the inability to use/cast them while kiting, thus making the item lose efficiency and the cost of the adc's survivability? in the end she is still an adc, a role that almost requires you to be squishy so you can buy dps items with low survivability besides your own positioning to keep you safe. also another issue i can see coming is the issue of her ult being stuck on one person. what would happen if her soul bound is afk, dc, or rqed? her ult would be unable to be used the rest of the game and she would love effectively a third of her kit, the health damage from her w passive with the soul bound and the active of her ult as an intiation/save ability. im not saying kalista is a bad champion in any regard; however, i believe riot should look into these hypothetical situation in which it could change the results of games. ty for your time. have a nice day.
