I didn't think of using the arrow keys, thats a good idea. And as far as the macro's go, just to make sure I'm understanding this fully, I should have a macro on each toon for casting spells? For example, a warlock would have one that did:

/cast DoT1
/cast DoT2
/cast shadowbolt
/cast shadowbolt

And the pally would have one of a similiar rotation?

I've watched a couple youtube videos, but they only show the people playing, not actually how its set up. And all the guides here show all the different ways of setting up, and examples on each individual way, but haven't seen one that's a "This is how I did it, and here is my setup:" kinda-deal.

Right now, I've just got a pally and rogue, set the pally as my Master. Kinda difficult in fights, because when I walk up to a mob, I can't just attack. I've got to move beyond the mob so the rogue will be in range. Is there a better way of doing this? Such as, a macro that will somehow tell the rogue to walk to the mob, and THEN start the attacks? Otherwise before I get to dungeons (and during dungeons) It'll just be a tank with a follower.
