Cant be more wrong, some ppl know nothing but talk anyway.
This decision to block some countries doesnt have anything to do with Trump administration or any american administration or RMT or bots.
Veterans know, few years ago Innova/4game become distributor for another NcSoft product, probably one condition was limitation of NcWest influence in Europe&CSI.
During negociation(its an assumption it was on) for the momment, a part of Europe, mainly EU, is a common ground for both companies....for the rest block.
Simply put, NcWest lost some teritories to 4game...smart ppl from EU already cash out and left west servers.
Decision for this is in NcSoft Koreea hands...they decide when,who,where(except for American embargo for Iran,North Koreea,etc).
To answer why ppl dont like to play on Eu server....well, dualbox cost 8 euro/month, 3 acount 16 eur/month, 4 accounts 24 eur/month, 48 euro/party/month and so on.
