So apparently Yrel was originally Maraad's dead wife in our timeline and in WoD their roles were reversed?
Wtf they cut a fucklot of things. Wonder what happened.
I understand his dying words and sacrifice better then.
It was part of a large amount of what was cut/changed in WoD.
Originally, Shadowmoon Valley had a different plotline overall, though we don't know most of it. The reason we know this is because back in early alpha dataminers were able to find the overview maps of pretty much every zone (even those that were just basically grey untextured blobs) and Shadowmoon Valley had a different layout. Memory serves, most of the places that are draenei towns on live were actually either destroyed by the Iron Horde or Iron Horde camps (for example, the town, whose name escapes me, that is to the northwest of Karabor, was a massive Iron Horde habor/landing spot). There was also a charred scar of sorts through the zone to the front of Karabor.
The fight at Karabor was roughly cut in half. Maraad would have gotten injured at some point in SMV (memory serves, this is still referenced in live questing, though its not said from what). There was a Gilnean presence in the zone as well, complete with Tess Greymane herself there. They were looking for reagents to help with the Worgen curse which was apparently not quite as controlled by the ritual (done in worgen starting zone) as previously thought, and seemed to be a way to explain why the Worgen had been pretty much non-existent, story-wise. The worgen were also involved in the search for Yrel's sister, and Yrel didn't quite trust them.
Yrel and Maraad's story continued in Gorgrond, which was also massively changed, and unfortunately remained gutted (its one of the reasons why Gorgrond has such a slapped together "story" and why it has so many bonus areas). Originally, Alliance-side (not quite sure for Horde), you were basically traveling around the zone in a caravan sorta thing with Maraad, Yrel, those two dwarves, and a Rangari or two. Somewhere along the way, Yrel would be kidnapped, driving Maraad to rage. We would rescue her, and if memory serves Maraad seems to hint at...something, having happened, but I don't believe its ever said what (this was extremely early in the alpha and at the time people were still theorizing that Yrel may've been Garona's mother or something to that effect, due to Garona's relationship to Maraad. So...yeah...).
Horde-side, what I do know happens in Gorgrond is Doomhammer is more involved (I'm not sure if he's even involved at all in Gorgrond, I don't have any Horde alts). From what I remember, it was meant to help set up his eventual heel-turn in Talador, but instead that's just left in the air.
Also speaking of Gorgrond, the zone was shaped quite differently, with the Iron Docks positioned on the eastern coast instead of the northern, and the Grimrail train had an actual presence in the zone, going all over the place. In the ensuing reshaping, the train was pretty much wiped away and the docks moved.
Talador had some changes but not too many, as I recall. I think the nature of the Iron Horde's supposed superweapon changed, though, which is a pity because what they ended up with was rather dumb (just another one of those cannons they had, nothing more).
Spires had a few changing things, mostly due to the final decision about whether or not garrisons could be placed in other zones. I'm not really sure if Nagrand had any changes at all.
No recollection about FFR either.
