What a journey! This beast may well have broken our record for number of attempts .. finally downed on the 88th attempt! Congratulations to everyone and thank you for all your persistence, hard work and stubbornness .. this bugger was NOT going to beat us! (although we might stop poking him for a bit now!).
Along with the final boss kill for progression in this raid on Heroic, we also gained a new "Feat of Strength" achievement:
And I think that was one achievement we definately had to work for!
