Friendly Party 1&2 - Player - Mouse over - All in one

Guides UI and Macro
1

I’ve been overhauling my UI and I unfortunately lost a lot of my macros.
I had a Master’s Call macro for friendly party 1 (shift) + Party 2 (alt) - Player no mod - and a mouseover target. This particular macro took forever for me to get it to work.

I have an enemy one still that works shown below:
#showtooltip Concussive Shot
/cast [@arena1,mod:ctrl,exists][@arena2,mod:shift,exists][@arena3,mod:alt,exists][@target,nomod,exists] Concussive Shot
/cast [@mouseover, exists, harm] concussive shot

Everyway I’ve drafted this for friendly targets, I can’t seem to get the player or mouse-over to work. One of them will work but the other wont. Please any help would be greatly appreciated.

#showtooltip
/cast [mod:shift,@party1] [mod:alt,@party2] [@mouseover,help,nodead] [@player] Master's Call

Optimized version of your Concussive Shot macro

#showtooltip
/cast [mod:ctrl,@arena1] [mod:shift,@arena2] [mod:alt,@arena3] [@mouseover,harm,nodead] [] Concussive Shot

Awesome, thanks so much!

Do you know of anyway to fix this macro?

#showtooltip
/cast [known:Scatter shot][@mouseover,harm,nodead] scatter shot; [known:bursting shot] bursting shot

Basically, when I choose bursting shot it will show the tooltip and actually use the ability.
Then when I choose scatter shot it will show the tooltip and use the ability prioritizing mouseover but also just on my target otherwise?
