No, I didn't mean to imply that. I meant that if a ranged DPS gets the red beam, for instance, that person will be in the red beam and not the yellow as they would otherwise be, which will decrease the count of people in the yellow beam. So you might have to move someone to compensate.

For example, with 3 healers, 2 melee, and 3 ranged, your base distribution is 4 red (tanks + melee), 3 blue, and 3 yellow. If a ranged DPS gets blue and a healer gets red, your distribution is changed to 5 red (tanks + melee + the healer with the red beam), 3 blue (the other two healers + the DPS who got blue), and 2 yellow. You'd want to move someone from red to yellow to compensate.

The trick for the raid leader is to pre-calculate when they will have to make the callout, based on current raid distribution, so they can do it quickly. With the raid comp from above, you could figure on:

* If healers get both red and blue, move one tank to blue to compensate.

* If a ranged gets red or blue, move that tank to yellow instead.

* If ranged get both red and blue, move the other tank to yellow as well.
