Personally, the small rework with the familiar is... alright I guess. And I don't know if this is already implemented long ago, but the fact that the familiar only heal when its healing amount won't go to waste, or overheal in other words, is not great. I mean, it's good to conserve spirit, but if the character's health is say 200 and the familiar can heal 300, you'd die first before the familiar can even heal you. And this is hypothetically if you can't kill the enemy first without taking more damage than your HP. Which happen more often than I'd like it to be.
Yeah that's all I have to say. Hopefully you found a workaround for this 'cause man, the familiar might get useless.
