Instead this thread will focus on why a large number of Alliance players in particualar focus so much time and attention on the continent of Lordaeron and why they wish to take the continent despite any logical or illogical reason for why it will not happen.
Let me begin by saying that I am one of those players. I will do my best not be biased in this but if I do let my biases show I appologise.
For many of the older players our attachment to the continent began with Warcraft 2 when Lordaeron was introduced. As someone who enjoys stories about medieval societies I found Lordaeron to be a fun introduction, especially since it was described as an idealic Arthurian nation. The other nations also caught my attention. The spartan like nation of Stromgarde. The closed off and stuborn nation of Gilneas. The more sinister side shown through Alterac. And Dalaran, the mage kingdom.
In warcraft 3 all of them were either wiped off the map, closed off from the world, forgotten, and/or consumed by the Scourge. For players it was not so much that the Alliance lost the battles, in fact one needed to win the campaign to reach the end. But when players reached the end of the Alliance campaign we were greeted by the a scene that ecentially said, congradulations you lost.
From a story telling perspective this is not a poor means of telling a story, on contrary this ending made players care more about the story because we wanted to continue the fight. However, in World of Warcraft the Alliance is not given the opertunity to fight back in an attempt to reclaim Lordaeron except at Andorhal. The story for the battle itself aside once again Alliance players were put into a situation where we fought well, and then lost.
This is where we come to the problem. Since Warcraft 3 the Alliance forces on Lordaeron have been placed into situations where they are given two choices, run or die. In short and to be blunt, I am tired of being told to run. Other Alliance players I believe are also tired of this which is why they address situations (both legitimate and otherwise) that relate to Lordaeron with so much passion. Whether you ascribe this to role playing or to stubbornness for many players this might explain why they react the way they do.
In my opinion there is a way to rememdy this situation at least a little. Do to the reality that retaking Lordaeron is not a possibility from a story telling or game play rational in WoW I will not suggest that (at least not serriously). Instead something that I think most Horde players as well as Alliance players would approve of would work better in the life of WoW. Stromgarde. If the Alliance succeeded in retaking this city and giving the Alliance a situation where they can win and not have to run it might go a long way to easing this sense of loss that many Alliance player have held for some time.
I hope this made sense and I appologise for ranting :).
