I moved to NA servers on EU for a while, due to working nights, ect. However, the culture is -so- extremely different. I cannot stress enough how different and polar WoW-RP is between EU and NA.
They’ve a completely different way of doing things, acting and such. One important note, is say IC conflict is genuinely quite feared. People who say RP trolls who don’t like non-trolls, are often assumed to be racist IRL and such. If people don’t have LGBT friendly in their trp, people quite often are very cautious of them. Due to the -… Intensive political nature of NA, IRL. It’s taken heavily into RP culture.
This has lead to kinda a very- Extremely everyone must be quite friendly to eachother no matter the outcome, kind of RP atmosphere. And critics of lore, ect, are not welcome. - An EG is a San’lyn chilling in Orgrimmar wouldn’t be questioned there. Headcannon is just the way of life there, not only on Moonguard but Wyrmrest.
Another note is with ERP. They’re very open about it. - Which is why you’ll see most TRP’s there, listing their IRL age. It wasn’t for me and I joined a guild and discussed with them EU’s way of RP, standards ect. And they all seemed quite frankly- Shocked. Thinking we’re some Elitist demon for not promoting headcannons above lore, guilds banning ERP, ect.
So quite frankly, if someone goes to RP on NA. They can’t just expect an American version of what Argent Dawn is. It’s a completely different culture, both IC and OOC. It was personally not a culture I enjoyed there, I felt there were little rules when it came to IC, and a thousand rules when it came to OOC. And it just wasn’t an environment that was personally to me. But if anyone from EU goes there and kinda preaches our way of RP, I doubt it will go very well.
As a side note, from what I’ve seen as well. Moonguard is Alliance based, Wyrmrest is Horde based. Apparently Wyrmrest used to be strict on lore, but that is no longer the case, and they’re simply nowadays just a Horde version of Moonguard.
