Thanks Tasty.
Some of the issues I have:
-Originally using /follow macro and spread out keys, toons often end up facing in the wrong direction, and only fix is either get them on follow again or turn them using arrow keys, which inevitably faces one of the 3 the wrong way again....
-I use Jamba now for follow, and I can disable it, so I could conceivably stop the casters and keep moving the tank to the target. It just means more macroing and keybinding than I already have.
-In order to start DPSing with an ENH Shammy, I would need to use keys that none of the others have anything on, which will limit the number of spells I can use. Short of writing a whole new batch of macros with [MOD] I can't see a way around that. Ditto for healing spells.
-With everyone casting right now, I can run down my keyboard 1, 2 then 3 if anything is actually still breathing. I like the simplicity. Totems, mounts and a couple other general things are on NUMPAD. Heals for the potential resto shaman are SHIFT 1-5, with a designator for each toon. ALT is used mainly for mage stuff, ALT1-5 make food, water, mana shield, mana emerald...

I guess that's what I mean about needing help. To individualize the toons into 3 categories, don't I end up losing some of the utility of each toon just due to space constraints? Mind you, at this point I am still just using a Keyboard, mouse, keyclone and thats it. I'm trying not to have to buy a 125 key super pad thing....
