Will variations of Kindred's interface be used for future Champions?
Looking at how Kindred has to have the UI adapted for them, I think it'd make sense if certain future Champions had similar variants designed for their own kits. For instance, you could have a Dancer Champion who can pick one teammate at a time to be his/her "Dance Partner", causing their abilities to work differently with said partner. You'd be able to switch partners when you wish, but like with Kindred, it'd take a few seconds for the switch to complete so you can't cheese with it in team fights.
Think this could work?
