Macro's that are actually useful ?

Warrior Macro to swap Inner Beast and Steel Cyclon with Fell Cleave and Decimate when useing the appropriate stance

/micon "Defiance"
/ac "Defiance" <me>
/crosshotbar set "Inner Beast" 2 RAU
/crosshotbar set "Steel Cyclone" 2 RDL

/micon "Deliverance"
/ac "Deliverance" <me>
/crosshotbar set "Fell Cleave" 2 RAU
/crosshotbar set "Decimate" 2 RDL

The 3 letters work like so:

First letter (either Left or Right) dictates whether it's the left or right crosshotbar (aka you hold L2 or R2)
Second letter (either Direction or Aaction) dictates whether it will then be on the d-pad or face (action) buttons
Third letter (Up, Right, Down or Left) dictates which button the skill will then go on, either the obvious directional button or the appropriate face button (Triangle being up, Circle being right, etc).

Macro snip

Similarly, if you're on PC, you could use mine.

/macroicon Defiance
/ac Defiance
/e I will show you TRUE Defiance!
/hotbar action "Inner Beast" 1 10
/hotbar action "Steel Cyclone" 1 11
/hotbar action "Defiance" 4 3

/macroicon Deliverance
/ac Deliverance
/e I bring unto thee Deliverance!
/hotbar action "Fell Cleave" 1 10
/hotbar action "Decimate" 1 11
/hotbar action "Deliverance" 4 3

For hotbar action, it goes ability name, hotbar number (you get 10 hotbars), position on hotbar (1 is furthest left, 12 is furthest right).

Also, /e stands for /echo, which means only YOU see it, but it can have sound effects that play too. Like my swiftress macro for example.

/macroicon swiftcast
/ac "swiftcast" <me>
/wait 1
/p You cannot escape that easily <t>! Time to Raise yourself from the grave and Ascend into Heavensward! Resurrection incoming! <se.7>
/ac resurrection <t>
/ac raise <t>
/ac ascend <t>
/wait 59
/echo Swiftcast off cooldown - Emergency Ress available <se.1>
