We've decided to spend thursdays doing 10 man raids as three nights should be enough to clear all 25 man content.
Last night was thus my first 10 man Naxx experience. I was a bit anxious because we ran with 2 healers, another resto druid and I. It took us 4 hours to clear the first four wings but the only real trouble we had was completing the Momma said knock you out achievement on Faerlina(2 wipes). I wasn't specced for Healing Touch and just hots was a bit slow to keep up with her Frenzy. Heigan was very easy with two Wild Growths and so was Noth, Gluth and the others. Patchwerk wasn't any trouble either though I thought he would be.
We did two 10 mans to compete in the guild and the other team managed to clear all of Naxx and get a few more achievements done.
