This is the reason I pass the arrow keys to my 4 dpsers. You still have basic movement control to spin/close/open range. On two, you just need to mouse click in the window and you have full control even if your macros may be a bit pooched up from getting focus set on your lowbie. Setup a macro to make your 70's focus on himself and use that when you have to. You should be able to still use all of his macros then if they are written correctly.
