I cannot get this Mage marco to work.

I thought say shift-1 was set to change which bar is up ( shift 1-6 changes your bar ) and I thought cntrl 1-9 are set to your pet bar.

try using ALT or just plain MOD as your modifier, unless you already have that modifier used

/cast [mod] foo
/cast bar

per say you can use all 3 modifiers but it probably should be on a key not already bound to other features.

I think You have to change quick the focus to the leader. I do this with a Makro. Then do your cast-makro works with focus. This helped me out...

/cast [target=party1target,harm,mod:shift][mod:shift] Frostbolt; [target=party1target,harm,nomod][nomod] Fireball

You can add multiple targets to the macro, in the event that one doesn't exist.

/assist party1
/cast [target=party1target,exists,harm,mod:shift][target=target,mod:shift][mod:shift] Frostbolt
/cast [target=party1target,exists,harm][target=target,mod:shift][] Fireball

crude, but that way if your tank dies the mage will still nuke ther last target, or whoever they end up targeting. instead of [target=target] you could put [target=party3target] or any other party member. As long as you dont run into the macro limit, you could put a conditional progression of targeting leaders to fall back to in the event of a toon death. It's not flexible like the "TFL" setups, but still pretty powerful. If your tank dies, just pick up the next toon and fire away, and the rest of the toons should see that the tank has no target, and move to the next toon for targeting, which you are controlling. Since I still use a focus system, I think I will try to adapt this system for me, but all I need to do is make one focusing macro fallback, so the toons focus on someone else in the event of main death.
