Macro:
/equipslot 13 Hourglass of the Unraveller
/use 13
/equipslot 14 Bloodlust Brooch
/use 14
/use Reins of the Swift Stormsaber (Change Reins of the Swift Stormsaber to the mount you have)
Works flawless, just make sure to have already equipped trinkets with use abilities on them, like pvp trinket and battle master trinket...
Replace the macro with any trinkets you want.
Trick #1: To get rid of the sound, just go into sound & voice and the click okay, done sound is gone glow is still there.
Trick #2: If your stuck in casting animation just mount or attack someone.
