UNBIND
Kalista should be able to unbind from one of her teammates, so if the person she binds to goes AFK, her W passive and ult is practically useless. She should be able to unbind from that teammate and bind to another.

She used to be able to, but that ability was removed because it made no thematic sense. Kalista's entire reason for being is to hunt down and kill those who break their word; she shouldn't be able to just break pacts and make new ones on the fly.
It would be super dumb and broke. For example, early game bind to blitz free kills then late game switch to amumu chuck him into the enemy team for a 5 man ult. Sorry but that would be...
Good luck summoner!
