i find that shamans are really easy to use as the "slaves" so if your subbing in a different class, then make that your main, and simply use keypad for slaves and click on your off class, 20x faster than setting up weird macros for the same numbers, that can easily get you in trouble in a lot of situations. so id say keep a different way of controlling each class ie: shift + anything besides movement keys. ( i use shift + 1-9 for totems :> )
