I guess they didn't understand your question
I haven't used it myself but I think this is how it works. Let's say you're in a party with 5 people and they all have max hp iof 2000, and their current hp is as follows:
person 1: 1238/2000
person 2: 1107/2000
person 3: 780/2000
person 4: 1523/2000
Person 5: 1492/2000
You use recovery division on person 3 and heal them for 500 hp and then you have this:
person 1: 1238/2000
person 2: 1107/2000
person 3: 1280/2000
person 4: 1523/2000
Person 5: 1492/2000
From that point on, whoever has the lowest hp gets healed next, so person 2 would get healed next automatically.
person 1: 1238/2000
person 2: 1607/2000
person 3: 1280/2000
person 4: 1523/2000
Person 5: 1492/2000
And so on~
person 1: 1738/2000
person 2: 1607/2000
person 3: 1280/2000
person 4: 1523/2000
Person 5: 1492/2000
And in the case of a person being solo, which is why I think this skill is somewhat popular, it will automatically heal that person every so often for the duration of the skill.
