Literally why not make arcane orb not pull stuff you’re not in combat with? Ah yes let me have to pause rotation to reposition myself so I don’t accidentally pull more mobs in M+.
Honestly, I would rather they just got rid of it. They haven’t updated its VFX even once and it was first introduced all the way back at the start of WoD. They also haven’t addressed any of the problems with it and the way it travels across the ground. Seeing as they can’t figure out what to do with Arcane Pulse I wouldn’t be opposed if they just replaced Arcane Orb with it instead of Arcane Explosion. As it is they serve the exact same function atm anyway.
