Kalista ult concept
For the time I have been playing Kalista, I have noticed people tend to not know where to use your ultimate. Such as panic clicking to just use it, using it in a wrong way or going for whoever is farthest / nearest.
I have a small concept for her ultimate so the person being "ulted" is more aware of what to do.
Upon ulting your bonded teammate, kalista can "Target" ping an enemy, high lighting them specifically in red so they are more aware of what to do and who to aim for. Similar to how Rengar works.
