Maybe a form of healing that we can give our companions instead of using healing skill is to give a potion to them during or before the battle to heal them that way they die less.
Give a potion to our companions was a good idea , But what I'm trying to says is why the creators have to stipulate that if we're going to use a new skills. We have to restart a new game only? That why the new content he had brought in was a meaningless.
