When I first started leveling this shaman I knew instantly I wanted to make a healer out of it. For a while I left it on the shelf but when I got back on my little 20 something baby shamy the first thing I did was go on the forums and search for the best healing addons or the best macros. I use Vuhdo since then, others use Grid, but my point mainly is that since you can click on it, there is no need for a million macros. So my general advice is, install a healing addon of your choice and get a mouse with at least 5 buttons. No excuses. You don’t need a gaming mouse to be (not just a good but) a great healer. All you need is to configure the tools you have in your arsenal. Clean up your UI and run dungeons till you have a body memory of all your mouse buttons and all your key bindings. That said my minimalistic list of macros I use are the following.
1.What I’ve fondly named my OHSHIT macro. Your go to macro for instant greater healing wave.
4.Specific Dragon Soul Macro ( For Utraxion and Madness of Deathwing special button.I find it easier to handle that with the macro than clicking on Blizzards icon )
There are many macros out there for 1.Earth Shield 2. Purging or for 3.Wind Shear interrupting. I use Vuhdo for all of those. As of now I can’t find any reason to use more macros but if you happen to know of any please feel free to share and if you need advice of how to set up your Vuhdo to do all of the above, feel free to ask.
