We managed to kill a new heroic! After a few weeks of regular farm with a lot of holiday activity all over the place, we banded together and killed Primordius. It was a pretty fun fight for most players, and once the raid got in to the rhythm of refreshing mutations things went well.
The raid team is currently looking to add a second warlock, since they are very strong at the moment both in terms of output and utility. Contact Kafhealya or Ack to talk more, or just apply right away.
