So here is what I'm thinking:
Archemonde screen shoot with the three mini bosses. Ok that's super duper cool and awesome, but one major thing is missing. Like very major - Kil'Jaden. He is nowhere to be seen. Well not that Archemonde was seen anywhere else, but still. As far as i remember Kil'Jaden was the one so obsessed with chasing down the draenei and Velen. He was the one who manipulated the Orcs in MU to drink the demon blood and slaughter the draenei. So i started to wonder - "Where the hell is he in this whole story and why Archemonde and not Kil'Jaden?!?".
To me it seems that Blizzard is trying to resemble in some way TBC and the Battle of Mount Hyjal. However, if we stick to a bit with the lore, there is no way Kil'Jaden didn't understood that the Legion has stumbled on a planet with a lot of draeneis living on it. There is no way the news didn't get his attention. I know this will sound like "hey look another person that refuse to accept that Hellfire will be the end the expansion", but i really think that he should show up at some point after Hellfire, if Blizzard really want to resemble a bit the current expansion with TBC expansion. I think this is really good material for 3rd raid tier and the only logical choice for a WoW character that is with equal or greater power level than Archemonde.
What da ya guyz think?
