We're on a bit of a roll with this whole "double downing" thing! (don't get used to it ) ... we FINALLY got down the last boss in Highmaul Normal .. massive congratulations to everyone for your hard work and persistence .. nice to know that we can be more stubborn than the bosses!!
As an added bonus, killing the final boss on normal netted the guild another new achievement:
As we got him on only the second pull of the night, we then had a wander into Heroic Highmaul and dealt with Kargath no problems and then killed our second new boss of the night .. it was a bit of a tight squeeze at the end, but we got The Butcher (Heroic) on our second attempt.
Most excellent work guys .. well done!
