Let's be real. I am a strong independent Murican that only loves Texas more than the Constitution, but NA sucks compare to EU on this server. I wish it weren't true, but besides Coalition and Titans of War we don't hold a candle in PvE. And as far as PvP goes I will only seriously play with Euros b/c NA players are aids.
There are exceptions to the rules and I think some Americans are better than any Euro players. Opilol was a better healer than any Euro. Kronus can hold his own against almost any EU mage. Simoniz (who plays a lot of classes) is the best all around player I have met. But, besides the few outliers NA players are no where near as good as EU players.
