I think Argent Champion was more like, aiming for the bigger picture, in relation to WoW but also outside of it - if you get when I mean. Like, if you look at the races that make the Horde and their fantasy history before Warcraft (yes yes irrelevant, whatever), pretty much all of them were made to represent man's fears and evils in one way or another (undead? orcs? goblins? trolls?) and I do agree with him that a person who doesn't know much about WoW's lore beforehand and is into ''noble and heroic'' is more likely to roll Alliance than Horde (I'll start from myself - I had no idea what WoW was before I bought WoW while on vacation back in 2005 and because I didn't have net connection there, I had to wait until I got home to play, but in the meantime I read the original WoW manual cover to cover. Just reading about the Alliance and Horde races, what they are, what they do, etc, made me decide that I wanted to play the Alliance, especially under influences such as LotR*). If Blizz writers are doing what they are doing now on purpose I do not know but there might be some truth to what he says about them wanting to represent sides as good and evil for a specific purpose (such as simplifying the story to attract more customers?).
I do, somewhat, like the idea of not representing the Horde as the typical, classic ''bad guys'', nor the Alliance of typical ''good and noble'' side (hell, I would've been the first to side with Leyara and incinerate Malfurion to a crisp back on Molten Front if we had that option) but as of lately, sides have been getting really polarized, which I guess is the main problem here.
However, all that said, what did you expect. WoW writing is about as shallow as it gets. If anything, I'd want WoW story to be more engaging/deeper/with more immersion, especially as the current bland ol' Alliance but eh, nothing is perfect, and World of Warcraft is a video game after all, not a serious piece of literature.
*After all this time though, I still am sticking with the same decision, while I see the fun elements in playing an Orc, a Blood Elf, or a Tauren, I'd never want to play as a faction who sides with the Forsaken - video game or not, I still have some moral principles of my own irl that I like to always respect. If my guild were to change to Horde, for one reason or another, I think I'd most likely roll a Blood Elf.
Anyhow, coffee time!
While I try not to be a huge Alliance fan, I know that deep inside I am and honestly, I'd be all up for peace with the Horde but currently, I don't see that happening anytime soon.I'd expect an alliance fan to only see orcs in the worst possible way and forget how there culture came from a noble yet savage tribesman based people, some tribes having more rough traditions then other tribes, but they did come from groups that respected things such as the elements, the ancestors and the hunt.
