As European I can say it really depends on the time you log on to our servers. I was on vacation last week so I got to play in the afternoon and it was (is) horrible. Female avatars (I bet 99% of them are 13-year-old males) dancing naked (as far as that's possible in GW

) typing about how they want to f... etc. Other players offering to strip for money, a lot of scammers (selling white mantle emblems as means to be able to change the appearance of your cape) and overall immature behaviour.
I'm from Austria, thus German speaking (although I like English more and I think I'm not too bad at it

) and I'm playing in the German districts. The problem with those is - there is no language filter for German. We can use ALL slurs we can imagine, they'll never get filtered. Lots of players use very immature names (as I said, no name filters, so sl*t is possible in it's German translation etc.) and of course all those kiddies don't have any skill. Most of them are W/Mo and think they can survive on their own rushing towards any mob as soon as they see the red dot. Tactics? I think they never heard about it
Still I wouldn't want to change to the English districts, simply because I like to have guildmates and players to speak my mother tongue. It's far more convenient on TS or in the chat. As I'm working most of the time, I'm online from 6pm onwards and it gets definitely better then. Best time is late at night where most of the players are 18 and over and I've found most of the people on my friendslist at that time. The skill also increases the later you play

I had two wonderful groups not long ago on Thirsty and Elona (both done on the first try without any casualties, everyone listening and responding to "orders", everyone waiting for energy refill etc.) so people know about tactics if you choose the right ones.
To conclude my long rant - I don't think European servers are better in general. But they may be better for American adults who want to play with a more mature audience simply because of the time difference. So when you log on after work at 6pm ET, that's midnight over here and way beyond the playing time of our youth. That's why you get to play with the mature players who understand tactics and teamplay better and are .. well more mature.
PS: Concerning the poster who was surprised about guilds taking members pre-searing - is that so uncommon on the US servers? Quite honestly, I love to search for future members pre-searing. Anybody who is willing to talk to you there, who joins up with you for a tryout quest, seems to be more commited to playing in a team. When everybody soloes the tutorial, how should they know about teamwork? I found out it is far better to help somebody from the beginning - because he will A) be very thankful and thus is more likely to stay with you and B) because you can "shape" him much more towards your guild tactics and playing style. Two of our core players were bloody n00bs when I first met them and now they love the guild and playing together with us. On how to recruit - sometimes I make ONE call in the local chat (not ten in a row like others, I'd never join such a guild if I was searching for one, so I refrain from doing that - I sincerely hope my call is good enough to win over anybody really interested in it) and sometimes I just whisper to people without guilds but with interesting and unique names that sound like the player has some brain and maturity. I'll also never just invite somebody, a practice I have often seen and I would also never accept if I was still searching for a guild.
