If I were tempted to use these for my hunter it would be solely for the Kill Command/Cobra Shot/Cobra Shot rhythm that is key to keeping your Focus up and after which you generally kick in a Barbed Shot, but even then there are interrupts, Multi-Shots, and CC that get interwoven with the optimal DPS rotation and it’d just get messed up too often to rely on.
As I said, generally speaking you should just set up your bars in some rational way and use spam/trash mobs to reinforce your muscle memory for your rotation rather than use cast sequence macros, but if you think it’ll work for you, go for it.
Also, you want intricate? This is my macro chain for all of my targeted attacks:
Name: TGT1
Location: ElvUI_Bar10Button9
Body:
/dismount
/cleartarget [help][noharm,exists][dead][mod]
/targetenemy [help][noexists][noharm][dead][mod]
/click ElvUI_Bar10Button10
/click ElvUI_Bar10Button11
/click ElvUI_Bar10Button12
Name: TGT2
Location: ElvUI_Bar10Button10
Body:
/petautocaston [nogroup:raid][@focus,exists,nohelp][@focus,noexists][@focus,dead]Growl
/petautocastoff [group,@focus,help,nodead][group:raid]Growl
/cast [nogroup:raid,group,@focus,help,nodead][@pet,exists,nodead]Misdirection
Name: TGT3
Location: ElvUI_Bar10Button11
Body:
(empty - used for specialized targeting in raids)
Name: TGT4
Location: ElvUI_Bar10Button12
Body:
/petattack [@mouseover,harm,nodead][harm,nodead]
/cast [@mouseover,harm,nodead]Bite
/cast [@mouseover,harm,nodead]Claw
/cast [@mouseover,harm,nodead]Smack
/stopmacro [@mouseover,harm,nodead]
/petassist
/cast Bite
/cast Claw
/cast Smack
Name: Cobra Shot (typical of all targeted attacks)
Location: Discretionary
Body:
#showtooltip
/click ElvUI_Bar10Button9
/cast [@mouseover,harm,nodead][harm,nodead][]Cobra Shot
Basically I just have to clone that last macro for each of my targeted attacks and change the ability name.
It gives me “free” target updates (to the closest target in my forward cone) if my target dies or is mind controlled, good pet control (but I have to put the Tank in focus), and eliminates the 0.6 second delay in the Pet AI for pet normal attacks.
