Our only issues involved bad timing in ending phase 1, and some positioning problems in phase 2. On our kill the first was a non-issue. We managed to down him seconds before the adds were finished off and in time such that no more adds spawned.
With M’uru behind us we headed down to the Sunwell. We got in several solid attempts as we worked with the dragons and making up macros to switch among dps targets. I see no problem with assuming we’ll get him down before the expansion.
