Killing Kil'jaeden is one of the most fundamental moments in WoW.
- He created the Lich King/Scourge
- Him and Archimonde, mostly Kil'jaeden's doing, had sent the Draenei scurrying across space as he sent the Eredar and Legion after them.
- He is basically the leader of the Burning Legion until Sargeras makes a complete return
- He is the most powerful Eredar [that we know of].
- We last saw him at the Sunwell where he was nearly fully summoned to Azeroth.
- Him and Illidan both used each other for their own schemes
- He commanded both Gul'dans and orchestrated two Legion invasion of Azeroth, one of them being the most biggest invasions we've ever seen [The one we're facing right now]
- He corrupted the Orcs on Draenor which caused the mass genocide of insubordinate Orcs and Draenei
- Him and Velen were best friends. [However, this dialogue may suggest something more? Mentor/Apprentice? Brothers? Relationship?]
Honestly, if you're a Draenei, you have been waiting for this moment forever. This is for Argus.
If you are an Orc, your ancestors that were slaughtered on Draenor or used and tricked by the Legion to carry out the destruction of your world, it is time to avenge them and regain their lost honor.
If you are a Forsaken or a Death Knight, this is the hour to end the creator of the affliction that shall haunt you until true death.
If you are a Blood Elf, this is your time to take revenge for him nearly destroying your precious Sunwell a second time.
If you are a Demon Hunter, stand aside Lord Illidan and fulfill your purpose by slaying the Leader of the Burning Legion
