Metzen wanted the old Orcish badasses (rockstars) to return and they just came up with a nifty story to do that. Since they didn't want to reuse same old Outland (due to how Cataclysm was received) they came up with Draenor before it exploded. But how are they going to explain that? They decided on an alternate universe.
But please people stop speculating about more alternate universes in future expansions, I think WoD is simply an exception. An exception made so we wouldn't have to play on exactly the same Outland as in TBC. You do know that originally they had planned for Garrosh to resurrect all the Warlords on Outland? Yeah, the only reason they didn't do that is because they feared another Cataclysm, so instead they wanted us to explore Draenor before it was ripped apart.
That's all there is to it, no need for crazy theories that tie everything together. Heck, Blizzard never even thinks that far ahead. They just do what is cool in the present.
Viewing alternate realities is pmuch how Velen sees the future. It's also how the Bronze navigated the timeways.
If a mid-level Legion guy like Malchezar has "All realities, all dimensions are open to [him]," then why wouldn't the higher ups in the Legion have the same capability?

I think ill use that spaceship and ill find alternate universe where my character will stay without mindblowing blizzards crap about timelines:S
Once Garrosh comes from his forked reality into our reality our reality then forks and everyone is from that point on in an alternate reality, so everybody is from an alternate reality.
What if in their reality the Draenei are the cool Forsaken!
They made very sure everybody knew this wasn't an expansion based on time travel but one based on Draenor, and that time travel was just a vehicle to allow it rather than a focus.
If we find out "our draenei" are from another dimension, then all of a sudden there could be another 100 draenei settlements that drop into our universe, it just starts becoming muddled and I don't think many people find that interesting.
Playable Draenei could be the last of their existence that hasn't been wiped out of all created possibilities; which would explain why they are only aware of the current existence. This would of course make the new alternate time line with draenei in it of immense interest to KJ though, and I don't think this expansion is supposed to be a legion thing.
This expansion definitely will be a legion thing, particularly towards the end. We know the legion are already involved and Gul'Dan has drank Mannoroth's blood, I think it was Kosak who mentioned a line about how the legion won't be particularly happy when Gul'Dan tells them about them turning it down and Garrosh. They also said this expac will set up the next one and lead into it, which i'm pretty sure suggests the climax being the legion taking matters into their own hands.
I would like to believe that this expansion will flow into a legion themed expansion, but I guess I'm losing faith that it will happen.
I certainly don't mind the complexity of all this. I enjoy Doctor Who.
However, the average player doesn't even know basic events of history or read quest text. Isn't this going to be a bit much for a glosser-over light-reader to handle? I think that's a big portion of the playerbase.
