Be warned, I'm about to get nerdy in here. *Adjusts monocle*
No offence, but go play Warcraft 1 and 2. Haven't played WOW regularly in well over a year though I did play for a month after Cataclysm came out, so I might not be the most up to date in WOW's story but in terms of the original story I must have read and re-read the manuals and played the campaigns for Warcraft 1 and 2 well over a dozen times each. Warcraft 1 was my very first rts game, my introduction to the entire genre, I loved that game and its sequels!
Anyway, when I think 'Alliance', I think of this guy:
Anduin Lothar, the closest Warcraft 1 and 2 had to a main protagonist.
When the Horde came out of nowhere to slaughter and entire kingdom, tens of thousands if not hundreds of thousands of complete innocents being murdered and killed for no apparent reason. When the King of Stormwind was assassinated, the cities defences breached, and everything going all to hell this is the guy that stood up and took charge.
An old knight. No magical powers, no super strengths, just the last of an old bloodline doing his duty.
I think that's why I like him as a character. All the rest of Warcrafts protagonist from Warcraft 3 forward all tend to be super-powerful wizard-warriors with brooding and angst and all sorts of boring issues. Typical fantasy tripe. Lothar was an old soldier doing his duty and trying to do what was best for his kingdom. He was believable. A sympathetic character, and the artwork reflects that.
Anyway he rallied the survivors of Stormwind and fled north to Lordaeron.
He begged the northern kingdoms for aid, gathered an army, and formed the Alliance. That's right, this old bugger up there is the founder of the Alliance. Betcha' didn't know that!
Whatever the case he rallied the armies, called all the various nations and peoples to him, and led a war to retake Stormwind and push back the Horde. And in the final battle, he died. He died in an ambush when the then-warchief of the Horde ambushed him and like the King of Stormwind before had him assassinated thinking that seeing their leader, the so called 'Lion of Azeroth' killed would break the spirits of the Alliance. It didn't. It had the opposite effect, enraging the armies of the Alliance into a frenzy such that the Horde never stood a chance.
Later on his second in command, Turalyon, would lead one last major attack
(Warcraft 2: Through the Dark Portal) to sacrifice his life trying to close the portal once and for all and save his people as his mentor Lothar had wanted.
Anyway, point I'm getting at is that this is what I think when I think Alliance. Duty, self-sacrifice, honour. Horde is all 'FOR ZE HORDE' chest-thumping bravado, Alliance simply do what has to be done. I like that!
That they might be a little biased against the Horde is completely understandable as well. The events I just summarized happened not that long ago in Warcrafts timeline, many people still remember when the Orcs came and started slaughtering. And while the Orcs like to say 'demons made me do it' that's a damned poor excuse. Grom Hellscream in Warcraft 3 said straight up that the Orcs did it willingly, that they enjoyed it, and many of those Orcs are still alive and well in Orgrimmar. Next time you buy something from an Orc merchant in Org, ponder how many
(thankfully fictional) children he's killed.
So seriously, F***K the Horde. They get what they deserve. For Anduin Lothar!
