When we were doing normal sha (we completely ignore adds on heroic p1), the people killing adds are the ones that just came back with fearless buff from killing the crossbow guy, doesnt matter which dps.
the 5 people who get sent over to xbow guy will be the group killing adds when they come back, since they have fearless buff they're immune to fear and can stay out killing adds until the buff wear off, once the buff wear off they go back to DPS'ing sha. Of course this strat assume people arent idiots and able to dodge a few penetrating bolts.
