The method I posted is the only method that I've heard of anyone using to complete the encounter. You don't have to skip more than one burrow phase for this to work... one will be fine. One group said that they got him from 80%~ to 59% during the locust swarm WITHOUT heroism, so getting him under 50% with heroism should be easy.
Also, I think there is a hunter ability that stacks with tongues/mind-numbing, but I don't know what it is.
Also, this is the exact same strategy used to get the achievement on Herald in Ahn'kahet. His insanity can be slowed, and if you wait for a mind flay, you can have enough time to DPS 33%~ of his health. If you DPS him from 66% to 33%, you'll actually get TWO sets of insanity adds (10 mobs) at once... So take him from 34% to 0%, and you'll skip the entire second insanity.
