Having been a long time proponent of not using macros for my pally and being reasonably vocal on the subject on this board, here's my about turn lol. The macros presented here for tankadins just didn't seem to cut it for me as there were pretty big gaps where HS just didn't come up, so with no more further ado, here's my 1 button 9696969 tanking macro any thoughts appreciated

With a tanking macro I don't want any randomness, I want HS to be always up and I want spells cast as soon as they're ready so that 96969 is carried out. It has to be mashabble.

My rotation is:
Holy Shield,Avenging Wrath,Hammer of the Righteous,Judegement of Light,Shield of Righteousness,Consecration,some instant cast random spell

approach:
you need to create 8 macros, 1 for each spell and 1 /click controller, I put all these macros on the right side bar except for the controller which is just bound in bindpad

controller macro

/click MultiBarLeftButton1
/click MultiBarLeftButton2
/click MultiBarLeftButton3
/click MultiBarLeftButton4
/click MultiBarLeftButton5
/click MultiBarLeftButton6
/click MultiBarLeftButton7

and the macros in order

1 - Holy Shield
/startattack
/castrandom Holy Shield,

2 - Avenging Wrath <-- instant cast so doesn't affect the rotation too much
/castrandom avenging wrath,

3 - Hammer of the Righteous
/castrandom Hammer of the righteous,

4 - Judgement
/castrandom Judgement of Light,

5 - Shield of Righteousness
/castrandom Shield of Righteousness,

6 - Consecration
/castrandom consecration,

7- a little instant cast macro I grabbed from somewhere on this board
#showtooltip
/castrandom exorcism, cleanse, hammer of wrath, Avenging wrath, Avenger's Shield,divine plea,

place these on the right action bar in the same order and bind the controller to the same key as your team DPS key. I've found that this works pretty well. The nice thing is that you can see your rotation and easily swap in/out spells without changing macros by just swapping in another spell on the bar.

A typical boss pull for me is to manually Avengers Shield, Consecrate and SoR to build threat - then just start mashing this macro.

edit: it's important to remember to put a comma at the end of the castrandom otherwise /click won't move to the next spell
