Iirc KoL 1 does not heal the group, only the player.
KoL2 does however heal the group.
If this is not working as intended maybe the proc can be changed to Kiss of the Minion, this would allow donor pets to proc the group heal when the donor is active and all the KoL2 augs wouldn't be affected. Any response would be appreciated.
