Okay, I'd have to give it a go again. Oo

I only tried to burst tactic twice, but both times when the first insanity went off (boss was around 30%, one time 29% positive when first insanity cast completed.) the boss dissappeared and I got two insanities at the same time, instantly. Double amount of visages spawn at the same time, murdering my dk and me too the first time, second time I did the aoe thing, I survived but DK died still in a horrible way, then we figured it probably wouldn't work.

The third time I stopped at 45%, let the first insanity come, deal with it, do some damage, second insanity, deal with that, kill boss. But was a 2 minute and 25 second fight, the second insanity took too long as I lost a shaman. :<

Still weird how you got the boss to be targetable during the first insanity, casting the second insanity whilest for me the boss just ignored the second cast for me and just did spawned double visages on the first cast. :P
