Man, overpopulated server has been butchering my framerates in cities. It's so annoying! I wish they would fix crap like that. My fps is better during trials where everyone is going crazy and spamming abilities against hordes of enemies than in freaking Deshan. It's a pain trying to avoid cities all the times just due to the huge amount of player models there
From my understanding, there is one "megaserver" for US and another one for EU. Also, the consoles have 2 as well -- one for US and one for EU.
