And let's all keep in mind that Garrosh will be a boss in the final raid of Mists of Pandaria. We've got at least two large patches of content to show us what else he's got up his metaphorical sleeves. Theramore is the first step and we'll have an entirely new continent to ruin. He'll be up to a lot more by the time we come take his loot.
Now, if he declared that his diet in MoP would consist of the blood and flesh of Alliance newborns, then he might begin to seem as bad as Sylvanas, but thus far the Alliance have the killing of a scapegoat to look forward to, with the Horde's help. What a shameful way that'll be to end the expansion.
It is possible, but we don't know if it will happen.
The Dalaran in Northrend isn't going anywhere, the amount of work ($) it would take to remove it would be enormous. Of course Blizzard could outdo themselves, but how many times do they actually do that.
What on earth does Dalaran have to do with the war effort? It's supposed to revolve around naval battles. Introduce Kul Tiras for fuck sake. They're perfect.
"And what's the real lesson? Don't leave food in the fridge."
I don't think dalaran will go alliance because the pandaren hubs have portals to dalaran (including the horde hub). would an alliance city allow the horde to open portals to it?
we don't even know when jaina goes to the kirin tor. it may as well be by the end of MoP, when garrosh is already dead. she may spend the whole expansion non-neutral and turn neutral at the end.
Warlorcs of Draenorc made me quit. You can't have my stuff.
Bornakk posted this a while back addressing this very issue when people think moving on with the story "breaks" a timeline.
"You have to consider the changes with some form of leniency, while technically you could say that if the story progresses then we need to remove a bunch of the content from Outland and Northrend as those are over - but for numerous reasons, you can probably see why that would be a bad idea. This is the same type of thing that happens by just having a persistent world, just because one quest was completed where something was killed doesn't mean it vanishes from your sight forever. While a level 80 doesn't need to return to the locations of Outland and Northrend and can focus on the new stories - a new character hasn't helped defeat the villains in those areas so they still need to answer the call and fight them off (or in the terms people are tossing around, they need to level)." - WoWWiki Nothrend page
Now, I don't have enough solid evidence to say for certain that Dalaran will be moved. All we can really know is that Jaina is the new Kirin Tor Leader and she will not be neutral. You have the Horde fan boys that will complain about "losing" a faction/city but you have to realize... You destroyed Theramore... This is all beta and you people complain like it was just implemented on the live system. Although something seems that way based off of datamined spells or vague quotes, it doesn't say in black and white (or blue) that Dalaran is a new alliance only city and it will be moved. We can only wait for more detail and keep our heads on instead of going out for blood.
