When fight need 1 tank you sit a tank, when it requires 2 healers you sit a healer. The off-spec are your backups.
Now obviously you want to cover all the buffs, and if you are wise, you'll spread the tier tokens and armor type loots properly so it doesn't get distributed to the same people.
But then again, perfect lineup doesn't cover talent, so go with the best people.
