Righto.

I'm loathe to actually post this, but my problem here is driving me crazy and I could really do with some advice.
I've searched the forum several times and can only come across snippits here and there that apply.

I have a five box crew. Pally tank and four Elemental Shaman. They only made 80 about six weeks ago if that
and have been working through heroics piece by piece. At the moment I have the Shaman all nuke spec and
have been using a combined set of all four shaman doing "Oh noes" spam heals when required. Usually only
needed on bosses. However, this is terribly inefficient for both dps and healing. Full stop.

Plus, this can make group damage fights, for example, the second boss in Gundrak rather problematic,
due to not quite having the group heals to do it.

I have one of the Shaman dual specced to Heal but holy hell, I seem to just plain suck at this harder than
I thought would be humanly possible. +2k healing, it just does not cut it when it comes to group healing.

My question is, what is the best way to handle a Shaman group healing in a five man situation?
And more to the point, from a macro point of view, what would be a good way to set up?

Should I have four separate chain heal macro's, targeting each group member one by one?
One single chain into the group does not do enough good in a tight situation.

Have I just become complacent after spamming the same dps setup for so long while levelling the toons
and just need to suck it up and get my shyt together?

Should I just accept that mana is now going to be an issue for the group where it never has in the past?

Would I be correct in saying that the healer will have to spam heal as much as the dps does?
Is there anywhere I can be directed to where this sort of issue has been addressed before?

Now I also have a decently geared Priest @ level eighty as well, but in a perfect world I would
rather keep the shaman together, to keep their gear and rep at the same level. If that is possible.
I am well aware of the decent aoe healing that a priest can do, and I have run the priest with this group
several times with moderate success. As I said, I would like to keep the shaman together.

Any assistance would be appreciated.
