Archimonde Heroic felled

Archimonde heroic is a difficult fight, and like a few in Hellfire citadel that difficulty is ramped up considerably for raid sizes near to 10 as certain abilities seem not to be designed for 10 man groups. In addition to the abilities we had learnt in normal mode we had a few new abilities to deal with from phase 2 onwards - and the abilities in the final phase make the encounter VERY hectic. It took a good few weeks for us to learn the fight and in recent weeks we were beginning to see lots of sub 20% attempts, but wihtout really feeling we were getting closer. A midweek discussion in guild yielded some new things to try, and on our first try of the night we managed to get him to 6% - we followed this up with another sub 10% try despite a few deaths - the next try he went down with only storm dying!
