Heyo! Fellow NA here as well <3
AD-EU is, for the last 2-3 years I’ve been on it, FAR tamer than the American servers. Very laid back, very chill, though I do come from Earthen Ring-US after it’s explosive community collapse so I may be alittle biased.
Horde-scene is VERY solid! Like the US, it’s largely guild-centric but you can still find a ton of walk-up RP. If your Ogre is looking into the Clan scene, it’s alive and popping. There’s a heavy Alliance lean, but there’s been quite a few VERY solid cross-over RP campaigns in the last few months.
Best advice I can give as an NA ‘crossing the pond,’ chill vibes until you catch how people talk. It’s a bit more conservative and reserved, but you’ll also find people are a LOT more honest and direct in how they talk. It can be jarring, but just about everyone you’ll meet is really solid.
In terms of Shamanistic/Clan style guilds I can think of:
Iron Wolf Clan is a post-Hellscream Warband-turned-Clan, and they take all kinds as long as you can fight. I would check in with their GM, as they have certain restrictions on Races.
Orcs of the Red Blade are another REALLY solid bunch, working on representing the best interpretation of traditional Clan Life you can get. Once again, race restrictions; I’m not sure their policy on Ogres.
And I’d be remiss not to include my own; the Frozen Paw Clan is a Thrall-styled New Horde Clan. Focused more on shamanism and honourable service to the world and the Horde, they have no race restrictions but are fairly nomadic.
Welcome to EU! Best of luck <3
