Which race would you feel is most suitable to be playable on both factions. Note that the criteria here is not necessarily neutral, but have members of that race willing (most likely, most believable) to bat for the otherside (whether exclusively in a faction, or friendly to both)
Allied Races
- Highmountain - have no beef with either race, good for netural, just not sure any of them might want to fight with the alliance.
- Mechagnomes - Quite wiling to work with both goblins and gnomes.
- Vulpera: - also deal with alliance characters, though the experience has been less favourable
- Mag'har - found peace with the draenei before the lightbound arose, however Azeroth Draenei and Lightforged are more accommodating. Void elves would be of great interest to the Mag'har Shadowmoon clan.
- Kul'tiran - The Freehold pirates that already join with the horde to give them their Tirasgarde base are a faction that would work with the horde.
- Lightforged: These feel a lot more neutral than all but the elven groups. Lightforged I can see work well with Blood elves, Nightborne, Tauren etc as Argus showed and quite happy to evangelise other horde races. Turalyon I think would be open to it, though likely another like the Nathrezim general would be the horde faction leader. I feel the light would be the one to insist the horde not be left out and appoint the Nathrezim or another to work with them.
Core Races
- Draenei: Frenemies with the blood elves. Some draenei still hate them with a passion, however others as seen in TBC and WoD rather like them a lot. While I don't see those draenei hating the alliance, it scertainly makes them ost likely alliance race to be neutral.
- Tauren: Faction of druids are quite soft on the Night elven druids, opening a door here. Grimtotem also work with the alliance and could be an enemy Tauren faction on the alliance.
- Humans: Alterac humans and Syndicate are likely candidates for horde membership, Cult of the damned cultists, drawn to the forsaken also possible
- Forsaken: Following Before the storm novel, we now know a number of forsaken are willing to reconcile with their former humanity and be received too by them, this could lead to either a separate faction of undead on the alliance or undead playing for either.
- Goblins: Many cartels, one could easily be on the other side or even on both sides, like the Steamwheedle could be on both horde and alliance, although when you roll a goblin on horde you start with the bilgewater. Also bilgewater could possibly also play fo the alliance especially if profitable, however, they supplied most of the horde's weapons of mass destruction that cost a lot of alliance lives, so not sure they will.
- Gnomes: Gnomes don't seem that alliance focused, more like go where the tech is, knowledge over allegiance sort of thing. Seen gnomes in places like Booty bay and other horde friendly zones, including Leper gnomes. Leper gnomes are a possibility to be horde only too.
A note on Elves:
Elves: I hestitate to add this, cos technically, void elves are blood elves on the alliance, and Nightborne are night elves on the horde. however:
- Blood elves: Not only are they most likely to have members that don't mind switching to the alliance as they've almost done several times also been on it before, they do have a faction of high elves very much into the alliance. Unification could be a huge motivation for blood elves to be on both sides, however those on the alliance will likely be high elves.
- Nightborne: Both factions helped the Nightborne, but we know they love the kaldorei (very proud of their heritage), whilst Thalyssra noticed Tyrande's aid was grudging during 7.1, she had a lot of willing help from other night elves, and her brief tenure on the horde makes Tyrande's reticence justifiable and unusable as an excuse. Bottom line, Judging from their history and what we are shown in 7.0.1 , there would be quite a number of Nightborne who'd happily prefer to side with the kaldorei and thus alliance, especially after seeing Sylvanas' horde, and having like minded souls amongst the Darnassian hihgborne and void elves.
- Void elves: Void elves really want re-unification with all Thalassian elves, especially blood elves, atm, they firmly want that to happen on the alliance side. However is their loyalty more to the alliance? the void? or unification, and can any number of these switch to another. Whiles an outside chance here, if it switches to unification, I can see void elves willing to play on the horde - however they'd have to have a reason to hate the alliance (or at least much prefer their people whole over faction loyalties.
- Night Elves: The least likely race to have members wanting to join the horde. As of WoT, I would say no Darnassian kaldorei would want to. It is possible Kaldorei like the Dreamwardens, Farondis or Moonguard would side with the horde because they're quite friendly with the Nightborne, and would do it through that, however it is more likely a good number of Nightborne would side with the kaldorei, which would allow those lot to still be friends with the Nightborne kin they've been working and not be enemies of the Darnassians.
- The Darnassians I can see having a faction on the horde under one condition. Once Sylvanas answers to her crimes, Tyrande's condition of peace is that a faction of the night elves sits on the horde council as well. Maiev volunteers for the job (which raises a few eyebrows - as she is both easily the most feared night elf but also the one mos tlikely to cause a Darnassian schism for which working on the horde would give her the means, Maiev has shown she is quite willing to take out Malfurion or Tyrande if she feels the Kaldorei would be better of for it). Tyrande's move ensures that the horde never work against the night elves, allowing Kaldorei to fully determine what happens on any ancestral land from Azshara to Feralas, and that her people are no longer threatened by either alliance or horde. Not sure how a night elf player would justify war mode, except that he /she hates other non-night elf alliance players, or hates those loyal to Tyradne/Malfurion and feels the less of them around the better.
