Please fix DFT + Kayn so that mid Kayn is viable again.
There was literally no problem with this interaction, and it makes sense from a gameplay perspective. DFT is still damage YOU are doing, so why shouldn't it proc his passive? Please stop "fixing" things that aren't broken, and give us a chance to experiment and learn what champions are capable of. Mid Kayn was by no means too strong or game-breakingly broken, so there was no reason to remove the DFT interaction.
