The Burning Crusade Hunter Pets
1.5 Pets
There are numerous pet choices out there, and much of which pet you choose is stylistic or situationally dependant. Certain pets are better against certain classes. Here is a breakdown of some more common pets:
1.5.1 Boars
Boars have a stun charge, which adds yet another form of crowd control. Their charge makes them good for chasing down runners such as flag carriers.
1.5.2 Wind Serpent
Wind serpents put out a lot of DPS and have good "focus dump" ability since their lightning breath has no cooldown. Their pathing is somewhat buggy so they sometimes back up instead of attacking even though they have no minimum range. Lightning breath is also a useful ability since it is natured based.
1.5.3 Cats
Cats have stealth, which is useful for concealing the hunter's position in battlegrounds and works well partly in conjunction with night elf hunters. NE hunters can stealth with their pets in arenas (particularly at arena start) in order to hide themselves completely.
1.5.4 Scorpids
Scorpids apply a DOT, which can be both helpful and detrimental. DOTs prevent the target from being crowd controlled such as by freezing traps. However, DOTs also make stings difficult to dispel; for example, keeping scorpid poison on a paladin in conjunction with viper sting can make the viper sting difficult to remove. Scorpids are typically seen as a requirement in high rated 5v5's because of their use in conjunction with viper sting.
