Do you mean that all in once, or two separate? As in switch to def. stance, equip shield, shield wall and a macro with berserker stance and equip weapon? Because I thought that shieldwall doesn't last if you switch out your shield. Not sure though, I mostly use it for spellreflect.
From my understanding (could be very wrong) shield wall continues even after swapping back to a off hand weapon so I was after a macro that does the sequence all in one.
Thanks for the response i'll try those out and maybe end up using 2 different macros.
