Once I got to VR Ranks, even before that (probably since L44 or so), I stopped using the Pets. With Surge, Elemental Wall, Impulse, Force (whatever it's called) and Boundless Storm, I have no room on the bar for a Pet Skill.
Even when I swap out some of my Destro staff skills, I still pick other skills like Crystal Shards or Mages Fury to take their place. On my Bow, it is the same thing, no room for a Pet.
