As I recall, keep an eye on your frenzy stacks; you want them at two. Kill Command on cooldown, don’t miss it.
And turn off the unnecessary pet abilities like Dash. Your pet has a bar (like a mana bar) to use its spells, you want your pet to Bite or Claw but not wasted on Dash or some movement speed thing.
Many players skip multi-shot altogether. Use your Mark before pull so other hunters can get theirs on other targets.
Every encounter requires some utility, so you do your part.
There are test dummies in the game for a reason, they are not only for the pvp players training muscle memory.
I’m sure others will correct me and not ridicule everyone.
In solo content, you’ve picked your pet to do stuff like slow the enemy with ankle bite; maybe for pvp too.
In group content, you want your pet to do damage like bite. You want to see that pet go bite, bite, bite. Your pet has an energy bar and can’t bite without energy.
During your group content, your pet will cast the extra spells like ankle bite or dash or, if a spirit beast, maybe a random heal on someone which means less bite, bite, bite. So, you have your pet UI with the marching ants and you turn off those spells.
Some might even turn off the marching ants on the spirit beast heal and make a macro so it is “heal me” and you have control for when you need it.
It is a simple way to manage your pet’s energy bar so that it is all spent on the dps portion of your game in group.
