I suggest you hang out in the Macro Forum just a little. There are a lot of people that share their macro’s that might give you an idea to combine abilities or change keybinds.
This is a good resource to start. Marcos: Condensing Your Physical Keybinds.
Read the beginning post carefully because it refrences an addon “Bindpad” you can however adapt these without the addon. Elvenbane is a wizard with Macro’s and is very helpful. I use a few macro’s from that thread and I have taken a few and used the base to turn it into my own macro. You can adjust modifiers to fit your taste.
One of my favorite ones is the Druid Utility Macro.
/cast [@mouseover,help,dead][help,dead]Rebirth;[spec:4,@mouseover,help,nodead][spec:4,help]Nature’s Cure;[@mouseover,help,nodead]Remove Corruption;[@mouseover,harm,nodead][harm]Soothe;[spec:4,help]Nature’s Cure;Remove Corruption
It puts Rebirth, Nature’s Cure/Remove Corruption and Soothe all in one mouseover keybind.
