Any US players here or is it all EU?

As someone who's only ever played TBC private servers, I thought I'd give this WOTLK server a shot. Any US have experience playing on EU servers and can offer me any wisdom on what that is like?

Thank you for your time and I'm excited to join the community!

I don't play on Lordaeron, so I can't speak to the effect of it.
However, on Icecrown, there's a sizable and active US community. Often times there will be plenty English-speaking Europeans who will join NA (I say NA instead of US because there are a fair number of Canadians too) guilds and raid at typical NA times too.

There's several NA guilds in recruitment and a good sum of icecrown guilds are carrying over to Frostmourne. Most EU players know English so its not really an issue.

Aslong as global will be enforced to English im fine with it
