On Thursday night on Razorscale I was on raid healing with another resto druid and a holy/disc priest. Raid healing felt a little wierd after the changes and had to adapt a lot from "spamming LB and WG raid heals with Nourish here and there" to "let's just stop here and think about it because mana is running low way too quick" and it didn't feel efficient enough either. Topping the healing meter was not too difficult but that should not be the point.
We went in 10 man and I was on raid healing again and changed a little tactic there. I started using Regrowth with stacking LB on tanks and using Rejuv in combo with Regrowth and threw some quick Nourish where it was needed and it worked out a lot better and it felt a lot better as well, and on top of it it seemed to be mana efficient as well.
On 10 man XT-002 just roughly from judging when tantrum was about to come, also on raid healing, used Regrowth again on everyone and it worked like a charm with Rejuv and Nourish again on the help.
My question is, as I just rerolled from a hunter for WotLK ... Is this something considered a good, efficient rotation for raid healing or there isn't such thing as long as your raid stays alive and the job is done no matter what we use? Or is there something more efficient way of raid healing with the new changes?
