Pretty much make sure everyone is stacked tight on that ugly purple line. Dodging as soon as you see that green circle. Everyone should see themselves moving ahead of the group on their screen in order to dodge properly. If you have BLMs separated from the group make sure they are far enough from the group that if they get marked they aren't accidentally mpking you with their divebomb. If someone is super fail at dodging just make them stand in the other dip. It is unlikely that they will get marked twice and one divebomb won't kill them unless they get knocked into a wall.
