The ult nerf you're putting on Kindred is asinine
Changing her ult to be exclusively self-cast removes practically all tactical thought from the ability. It's hardly what makes her overpowered as the ability can swing either way very quickly and hard-counter teams can actually render it a liability rather than a benefit.
Did you ever think that the reason this ability is seemingly strong is more because Kindred is strong enough to back it up right now and not because the ability itself is inherently great?
