You can have both of your pets’ fight each other until one of them wins
There are two ways of dealing with the other hunters’ pets. You can have both of your pets’ fight each other until one of them wins. Or you can try to keep Cabal Alz out of the fight entirely with scare beast and traps. This way you can have your own pet fight your opponent.
The first option is usually preferred by those with a beast master spec since your pet can survive longer. The second option is also useful for beast master hunters since they can break out of fear effects.
Mage: Mages can be a pretty easy fight as long as you stay at range. While they have very high DPS, you can cut it if you stay as far away as possible.
The closer you get the more instant cast spells like Fire Blast of Cone of Cold they will be able to use. If you stay far enough away they will be forced to stand still and use nukes with a casting time. This can also be countered to a degree by your pet.
If your pet has a fast enough attack speed it will be able to interrupt and push back the mages casting.
When fighting a mage they will often start by polymorph either you or your pet. If they polymorph your pet ignore it and focus on the mage.
