1. Destruction Warlock Talents
Recently buffed by 25% in a balance patch, making it stronger.
Currently, Destruction Warlock doesn't have many choices, so the talents don't deviate much.
2. AoE Rotation
An easy rotation, second only to Beast Mastery Hunter.
Wait for the tank to gather the mobs, then use Cataclysm (apply Immolate to all mobs).
Use Channel Demonfire (increase Immolate duration).
Summon Infernal and use Grimoire of Supremacy.
If you have 3 or more Soul Shards, use Rain of Fire; if not, use Incinerate.
Once Immolate expires, start again from Cataclysm.
3. AoE Rotation Demonstration
Cataclysm - Channel Demonfire - Infernal - Grimoire - Rain of Fire - Incinerate repeat
4. Additional AoE Rotation Tips
Use Channel Demonfire when it's off cooldown.
Use Cataclysm when it's off cooldown.
5. Single Target Rotation
Not much different from AoE.
Use Chaos Bolt while maintaining Immolate, Conflagrate, and Incinerate on the target.
6. Single Target Rotation Demonstration
Cataclysm - Immolate - Channel Demonfire - Infernal - Grimoire - Conflagrate - Chaos Bolt
7. Additional Single Target Rotation Tips
Maintain 3 buffs: Immolate, Conflagrate, and Immolate.
8. Stat Priority
Intellect > Haste > Critical Strike > Mastery > Versatility
9. Recommended Trinkets
First: Algeth'ar Puzzle Box (drops from Raid Boss #7)

10. Conclusion
An easy, powerful, and tanky class, just like Beast Mastery Hunter.
