I got 5 druids and eclipse is pretty simple... you need addon that shows procs then you need 4 buttons for it

button1 - this is for tank/healer rotation and for moonkins it's /cast wrath in actionbar1 and /cast starfire in actionbar2

button2 - /swapactionbar 1 2 for moonkin 1
button3 - /swapactionbar 1 2 for moonkin 2
button4 - /swapactionbar 1 2 for moonkin 3

when you get proc from moonkin just click your swap button and continue spamming until you get new proc and then continue your spam...
