Much of early World of Warcraft was a mess, plauged by a lack of direction in what was actually being done. The initial game was scoped to include Northrend, Outland and the Emerald Dream with some prototyping done on the later two before the team got some much needed focus and began focusing on delivering the game. Some elements of the lack of experience with the MMO genre, particularly 40 man raiding (which was essentially a random number picked because it felt epic) survived into classic…whereupon the reason 40 man was a bad idea became immediately apparent and it was nixxed in TBC.
Part of this process was the switch to the faction system of Alliance and Horde. This was directly inspired by the three faction system present in Dark Age of Camelot. You can find the details in the October 2001 chapter of John Staats ‘The WoW diary’.
“At the meeting, Alen Adham announced a resolution for the subject of good/evil races playing together. He thought the concept of “us and them” reinforced a system of community and camraderie, and by prohibiting orcs and humans to group or communicate within the world, the races inherited more personality. This philosophy was directly influenced by his experience playing Dark Age of Camelot…”
The game shipped THREE years after this decision. Hardly last minute, nor does this invalidate my statement. Once the faction split was decided upon, diversity and differentiation were implicit in giving those factions narrative weight.
Attempting to argue having BEs and HEs in their respective factions would contribute to faction character is nonsensical given we now have a whole cadre of neutral races in the Pandaren, Earthen, Dracthyr and shortly the Haronir. Whilst they are definitely neutral, conceived of and introduced as such, the cost effectiveness of introducing the same race to both factions does slowly degrade the differences between them. This is alleviated by the fact that these ‘neutral races’ are individuals joining the factions rather than their societies and states but not eliminated.
The Void Elves, whom I am sure we can all agree are not High Elves, normal skin tones be damned, achieve the goal of having a faction of elves with competing ideals to the Blood Elves and in a far more interesting fashion. Void vs Light is implicitly more interesting than ‘a decade ago you drained magic from mana wyrms for a year or two’. In other words, they render your argument about HE making the Alliance more interesting redundant. It’s like arguing for a candle when you have a lightbulb.
The Alliance High Elves have never been numerous in Alliance lands.
The ‘major’ settlement in Outland is NAMED after a particular elf and is mostly inhabited by Humans.
The Silver Covenant is a grouping mostly comprised of rangers (hence why the leader is the Ranger General), some mages and a few individuals from other classes. They are not a functioning society. And all the places people argued Alliance High Elves were numerous have been destroyed, from the lodges to Theramore to Dalaran itself.
And they weren’t introduced as neutral. They were introduced as a core Horde race, which makes sense as every neutral race starts with the same origin and the player is tasked with making a decision on where to go by their society, that society however is perceived as being outside the Alliance and the Horde.
The Pandaren, Earthen and Haronir are not members of either faction, individuals within those factions are AND they can always go home again afterwards. The Dracthyr have aligned distinct wings with each of the factions, but there is no sense that the Dracthyr as a whole are aligned with either faction.
In contrast, the Kingdom of Quel’thalas, the vast majority of the people, the city of Silvermoon, the Farstriders, the Magisters and the Sunwell are all Horde aligned or Horde territory.
The Blood Elves aren’t a neutral race because they just aren’t neutral. They are Horde.
To argue otherwise on the back of a handful of traitors is ludicrous.
