Granted, LB requires 11s to explode, and then every 1.5s later, but if the fight will last longer than 20s (and none of the adds die before that time), it's better DPS to keep LBing if all of the 'first batch' will explode their LBs. If there's something like 4 adds I use Blizzard as filler between the 4th LB and the next wave of LBs after explosion.

Also, if there's one among the pack of adds being AoE'ed that's stronger/need to be killed earlier than the others, then target him for the Hot Streaks that you will get. Of course this one works when there's alot of adds that don't die that fast (In Uld25 mainly). Sometimes when there's more than 7 I just keep tabbing LB (phase 2 Black Knight, Freya adds, etc) - 17k dps on Freya trash don't lie :p Try it out.
