I had a Kalista bind to me once. Thing is though, I was the JUNGLER.
Were you an initiator, or a duelist?
While uncommon, Kalista doesn't always have to bond with the support. It'd be one thing if it were the toplaner, but a jungler is acceptable in some cases.
I was Malphite, the initiator/tank. When you put it that way, it sounds pretty strategically strong...
