Tonight was a successful raid! We got Heroic: Chimaeron! I was healing the MT and the double-strike tank. The MT just needs to be above the Low Health debuff while the double-strike tank needs to be topped off as quick as possible. We had a paladin Lay on hands rotation for quick tank switches and everyone just did a great job.
I've made the switch from haste to mastery and tried a spec without Furor where I went for Genesis instead. Might take a while to get accustomed to the new mana situation and it certainly is a big change when it comes to such a huge haste drop.
