As much as I love Warlords of Draenor's focus on draenei and draenei culture, I'm very much interested in the world the draenei originally come from, the world of Argus. Especially when we're told several times that the draenei crystalline magical technology worked better there - that they had vast cities, an elaborate and storied magical culture so amazing that it attracted the attention of Sargeras the fallen Titan himself. I've wanted to get to see Argus for years, ever since I ran into members of the Argus Wake outside of Alterac.
What does the planet look like now? Is it a blasted ruin, or do its towers still rise imposing, as the bastions of the eredar warlocks? I'm just totally nuts about the idea of getting to see it all. As much as I'm jazzed for Draenor, part of me wishes we'd gone to Argus instead.
