So far, in Dragon Soul, we´ve managed to take down the normal difficulty setting.
This happened for our main raid team during the very first week.
We have of course also managed to kill the first heroic encounter on the following reset: Morchok.
Good job!
The second raid group are doing great as well.
Having taken down the normal mode difficulty is no minor task, and wouldn't surprise me if a heroic mode has fallen by their might as well

So good work guys and girls!
UPDATE: Group 2 catches up with Group 1 in progression - Morchok hc down!
We´re about to enter 2012. I'm counting on making this as great as all the previous years we´ve spent together, and looking forward to facing more heroic modes and not to mention; Mist of Pandaria with the known faces within the guild.
I wanna wish you all Merry Chrismas and a happy new year, and lets together make the next year(s) as great as it has been since forever here within Omen.
