Pet responsiveness, really. I mean trust me; I've tried every macro in the book. /Pac Steady and /Pac Guard. The Ol' /Pac Stay or /Pac Heel. Quite frankly even upon spamming an order, their Embrace will interrupt, but they'll just go right back to casting it and ignore the macro order or order outright. Precious seconds are precious seconds. A lot can happen while I'm standing there like a Star Marmot mashing Fey Illumination and Whispering Dawn.
