Kalista initial problems on release

The largest issue with Kalista is her soul tethering passive. This passive relies on the cooperation of a teammate whom often you don't know. I feel that this implies too much trust upon an unknown player in the fairly ackward league community. The player can disconnect and you find yourself unable to use your ult unless it fancies you to drag the players disconnected body around your base. The system is broken in this way because you cannot re-tether yourself. But also there's an issue of deciding when it's appropriate for you to be able to re-tether because the system could be abused by asking your partner to reconnect in order to achieve a different partner. In addition, Kalista can drag players without their will, if for instance you're taking blue buff, you can be ulted and she may take the buff without your consent because you simply cant control your character for a few seconds.(she can also be a complete troll and disrupt any plays you try) I don't know the proper fix to this but i feel there needs to be one.
