Sadly there is a right and a wrong way to do it. The first one I joined, it was definitely the wrong way, but after a few, I was determined to do it the right way. Mine has been working since 2016 because we strive for the “Werewolf” theme, and I’m of proud my members for not falling into the negative stereotype.
I do enjoy racial guilds, mostly because you get to explore aspects of that race’s culture in so much more detail, and you all have common goals and lore to collaborate on. For worgen especially, the canon lore has founded a culture of packs and hunting even among Gilnean worgen, which can only really be explored with a group of worgen. Other races could get bitten in the chaos, and are a liability.
