The question stands in the title. I've heard the Observer should pull more dps than every other pet, but after some testing on dummies, it seems like they're all more or less dealing the same damage over time. I did not use optic blast on cooldown, is that the reason why Observer would outperform other pets?
Also, Voidlord seemed to be the top damaging pet in my testing(10 minutes each on dummy, debuffed with curse of elements for each pet), which appears mighty weird as it should be the tanking pet.
Any input about whether there's any remarkable difference between pets at all, is welcome.
