Doesn't Kindred seem like the type of character who should have an execution ultimate?
Like they're supposed to be literal death right? So shouldn't they have an ultimate that kills and not an ultimate that keeps enemies alive?
It would also be a good chance to make Wolf feel more important in her kit, by making it that he executes the target. Something like upon activation, Kindred places a special mark over an enemy champion. This mark lasts for up to 10 seconds. If an enemy falls below a certain HP threshold, 1 of 2 things happen.
If they are not in Kindred's Attack range upon hitting the threshold, Wolf chases the target, and upon reaching them, bites into them, killing them. But if they are in Kindred's attack range, Kindred fires a special arrow at the target, killing them. If the enemy doesn't fall below the HP threshold, the mark disappears, and Kindred must kill them using Basic attacks abilities.
