My 2 ISBoxer 2 Step Macro and Setup

[Ualaa]

BTW: If you like to be a little more flexible with changing talentspecs in game you can always create a spec change keymap targetted to current window only.

Step 1
  Action:
    Warcraft macro action -> "/usetalents 1"
    Join Group "Druid Resto" > "Druid - UberDruid" <--- (Obviously this is aimed directly at a character not a slot)
    Leave Group "Druid Tank" > "Druid - UberDruid"
Step 2
  Action
    Warcraft macro action -> "/usetalents 2"
    Leave Group "Druid Resto" > "Druid - UberDruid"
    Join Group "Druid Tank" > "Druid - UberDruid"

Could do this to swap stances equally well, and probably more useful too.

I've got something similar.

It also includes:
/Equipset PvP
/Usetalents 1

And:
/Equipset PvE
/Usetalents 2

I just named two sets of gear, using the in-game equipment manager.
