Hmm, I play and trade in all Districts (American International and Europen). What I do notice is that some Americans really do end up flaming and cursing like mad at the slightest provocation. Although to say I have never had a bad trading partner anywhere becaus eI am polite and dont insult people. If someone would do that to me, then I would refuse trade (Buy
OR sell) anyways.
I know from personal experience (been to the US a few times and am in a mostly US/Canadian guild) that most Americans are frinedly and no different than any other people... but there are enough idiots who think that because they interpret part of the American constitution in a specific way that it is their "god" born right to insult and abuse others. Those are more often the loudest and most prominent ones who drag the rest down.
The other thing which puts the US down is the current political leadership. People representign their country either put a good light or a bad light on their country as a whole for many people depending on how things are managed.
Well, thats enough bad/good things about the US. If anyone is insulted by the things I typed, then im sorry. It wasnt meant to be insulting. Just explaining the general Europen view of current US from a neutral standpoint (ie I personally dont care for some of the views)... And now for something completely different (quote for all you Python fans out there

).
International districts are too empty for me most of the time to be of any use (except for Vizunah square or Unwalking Waters missions).
European districts seem to be less laggy for some reasons (for me obviously, but also for my guildys from America from what they say) to the extent that the complete guidl was Euro server based back when you couldnt move freely between the districts. There are noticably less flaimbait and insults flying over the local chat lines, and if someone does start crap I have often seen half a district type gtfo or stfu to the starters. lol
As to missions, I havent failed more than once with a German PUG. If we do fail, then most of the players stay in the group and work on addapting to the sittuation before retrying and succeding, insted of shouting insults and ragequitting like I have experienced in enough US/English PUGs. They just seem to be more laid back and relaxed to me.
