Epic/Funny Battle

So I'm in Zul'aman and we are fighting the first boss, which is the one that casts the thunderstorms that you need to avoid getting hit by. The the healer is have a tough time keeping everyone healed up, but manages to keep us alive as the other two dps seem to have trouble avoiding the thunderstorm. We manage to get the boss down to really low health and a thunderstorm takes out everyone except me. I'm at maxed range so I go full out on him managing for a second or two to avoid being killed by him and getting him down into kill shot range. I disengage away from him and just as I land get off a killshot. BAM! It kills him as he kills me.
