In our 10 man, me (affliction lock), dot put the 3 dots on each add, and refresh just the UA and Corrr with fel flame when they are at like 20% hp and the dots are falling off.. it kind of sucks that you cant get soul shards back from the adds tho =/. The rest of my raid just ignores adds unless i get put into the construct.
Just let people who get an add on them move to the boss and cleave them down and move them out once they are low on health (or not if you don't care about the damage and heals on the other adds) and place them somewhere where you can pick up the puddles easily in phase 3.
Your spriest and aff lock should be multidotting those adds. I play spriest myself and there is no reason at all to not put a SW: Pain on them to increase your chances on procs. Elemental shaman can just use CL.
If you are unable to cleave them down you are doing it wrong.

Why? In our 25 man raid they just go down by cleave/multi dot damage, no one is focussing on them since you are focussing on the boss and monstrosities.
Cleaving will also increase your overall dps instead of focus firing on adds or whatever.
We in 10 man guild have a rule that every DD takes down its own Add and help the healers getting rid of their Adds. Actually I help out everybody, but it never was a big problem for us if the rest of the fight is played nicely.
