I've never full on automated this because I actually had fun driving it, but here's the hotkeys I used to do it
Hotkey 1: Summons pets if you don't have a pet. This works for Necro, Mage, Ench, Shm, SK
Line1=/noparse /dgza /if (!${Me.Pet.ID}) /alt act 2684
Line2=/noparse /dgza /if (!${Me.Pet.ID}) /alt act 2810
Line3=/noparse /dgza /if (!${Me.Pet.ID}) /alt act 2847
Line4=/noparse /dgza /if (!${Me.Pet.ID}) /alt act 2605
Line5=/noparse /dgza /if (${Me.Class.ShortName.Equal[SHD]}) /if (!${Me.Pet.ID}) /alt act 2806
Hotkey 2: Hastes pets if you're a mage or necro
Line1=/dgza /alt act 2682
Line2=/dgza /alt act 2805
Hotkey 3: Vox Specific, casts DA then runs to the spot
Line1=/pause 21, /dgza /alt act 2821
Line2=/dgza /nav loc 748.93 -403.60 0.62
Hotkey 4: Come to me
Line1=/dgza /nav spawn ${Me}
Hotkey 5: send pet on target.
Line1=/dgza /pet attack ${Target.ID}
I basically drive on one toon, and spam the summon pet button, and laugh as all the pets murder my targets. It's quite entertaining.
