Have a look at this please:
Bird class pets seem to be the worst here, but other pets are far from reliable as well. Note how the golem in this example does not even have swiftness, dodges, or even consciously tries to avoid the pet, while the pet does already have its 30% speed boost traited. Besides this, many of the pets' f1 skills do have unnecessary and long activation times, which means they also lose precious time on their targets, should you decide to use them in pvp. Experienced players *will* take advantage of this.
