Stop attack intimidating shout macro
A macro that starts with "# show none" will show no feedback.Otherwise the first /cast, /randomcast, /castsequence, /use, or /random use command will be used to show feedback for the macro.Mouseover sunder - this macro will sunder the mob your mouse pointer is over without losing your current target (the mob must still be in melee range, of course).It also checks if the target is actually hostile and alive before doing this.If you have a shield equipped and are in Battle or Defensive Stance, use Spell Reflect.If you are in Berserker Stance, it will change to Defensive Stance so that Spell Reflect can be cast. I use the HS/SA one first to get excellent threat (make sure you've got the rage, otherwise simply sunder), then the revenge/SB to give mitigation and threat, adding in the other now and then...If you do not, it will equip the Shield, so you can simply double-click it.This is important because it allows 4 Shield Slams reliably off one trinket use.
Put them in the same slot on their respective bar and then just spam that button/key and it will perform the appropriate logic as it switches around from bar to bar.
Since you will use the SS at the 0 second marker, then at the 6, 12, and 18 second marker, with regular server lag you can still get 4 in safely.
