So whenever people are talking about an aoe cap of 5, and I agree this should be a think, how do you determine which 5 get hit in a group of say 15?

Just random 5 people for each seperate aoe, the 5 closest to the center, 5 with highest hp?

Been wondering about how to make it so it doesn't instagib 5 people everytime, but also not to where it makes aoe's completely useless if they get spread out on different people.
