Having a good User Interface is key to performing at a top level. Everyone should build their UI around their own needs. Think about what you want to see, and don’t just copy someone’s Interface.
Here are some Add-On recommendations that everyone should consider:
- Weak Auras 2: Great Add-on to track every kind of buff & debuff in the game that basically every top-raider uses.
- BigWigs/LittleWigs: BigWigs is a great BossMod that is easy to setup and very customizable. It usually is the most up-to-date BossMod. LittleWigs does basically the same for dungeons.
- Plater: Good nameplates are really important for every class and even more for DoT-classes. Plater is one of the more popular Nameplate Add-On choices.
Some useful macros for Destruction Warlocks are curse location macros which cast the spell at the location your cursor is when you press the spell.
Summon Infernal Macro
/cast [@cursor] Summon Infernal
/cast [@cursor] Shadowfury
Cataclysm Cursor Macro
/cast [@cursor] Cataclysm

Also, some useful macros you can use are mouseover macros.

Soulstone Mouseover Macro

Spell Lock Focus Macro
/cast [target=focus] Spell Lock
Weakauras are essential if you want to take your gameplay to the next level and track abilities properly. I really advise heading over to wago.io and having a look at some of the destruction weakauras and importing and trying them.
