Interface
For your Interface I would recommend using Weakauras and Bigwigs.
Weakauras will give you the opportunity to import a lot of helpful visuals/alerts/timers to keep track of your cooldowns, buffs and debuffs.
BigWigs for having a boss mod helping you to plan your cooldowns ahead of time and be prepared for certain abilities that are about to happen.
Macros
Here are some useful Hunter macros everyone should have:
Aspect of the Turtle Cancel Macro
You can cancel Aspect of the Turtle by pressing it a second time but it has a small delay in case you click it too many times in a short period of time. This macro removes that delay so use carefully.
#showtooltip
/cancelaura Aspect of the Turtle
/cast Aspect of the Turtle
Misdirection Mouseover/Focus Macro
Misdirection is an important ability in Dungeons but also in Raids: This macro will cast Misdirection on the target you are currently mousing over. Otherwise it will cast on your Focus target.
#showtooltip Misdirection
/cast[@mouseover,help,nodead][@focus,help,nodead]Misdirection
Party Leader Misdirection Macro
This macro will cast Misdirection on Party Leader.
#showtooltip Misdirection/cast [target=party1] Misdirection
Spirit Mend heal Mouseover Macro
#showtooltip
/cast [@mouseover] [pet:Spirit Beast] Spirit Mend
Spell & Pet Attack Macro
IT'S IMPORTANT FOR BM HUNTERS TO USE THIS MACRO FOR EVERY OFFENSIVE SPELL.
The auto-cast system from blizzard is super slow on pets and you might miss out, so make sure to use this macro.
Another important topic is the pet attacks. You should macro them into all of your abilities when you're using a pet to guarantee the pet will use them on cooldown and not miss out on damage.
Here is one example for Kill Command. It is recommended to macro these into every important ability while using a pet.
#showtooltip Kill Command
/cast Wake Up
/petattack
/startattack
/use Kill Command
/use Bite
/use Claw
/use Smack
/petattack allows your pet to instantly switch to your target and start hitting it
/cast Wake Up is in case your pet is in feign death mode (can be used after taunting a mob in Mythic + to lose aggro)
Command Pet Macro
#showtooltip Command Pet
/use Primal Rage
/use Survival the Fittest
/use [@mouseover,help,nodead][@player]Master's Call
Combines every pet command ability in one button depending on which type of pet is summoned.
Cursor StealTrap Macro
#showtooltip
/cast [@cursor] Steel Trap
Allows you to instantly use Steel Trap where the cursor is.
Mouseover Barbed Shot Macro :
#showtooltip
/cast [@mouseover,exists] Barbed Shot; Barbed Shot
Allows you to cast Barbed Shot on a target by just putting the cursor on it, no need to target it. If the cursor is on nothing, it will just cast it on your target instead.
Weakauras
Having good weakauras can really help you out a lot with keeping track of all the important stuff.
The best is just to find weakauras fitting your own interface preferences and play style.
