You must be trolling I guess, because the term ‘Allied Race’ refers specifically to PLAYABLE races.
Alliance helped the Sethrak a good bit too in BfA, so it would make sense that they would at least be neutral. My primary reason for wanting them as Alliance exclusive back in BfA though was because Vulpera were obviously going to be Horde eventually, and I’ve always pictured a Sethrak sitting on the ground with a bulging gut and a Vulpera tail dangling out of it’s mouth
