Rightfully so. While I personally do like international servers, there's valid points: World chat/chat in general will be a mess due to everyone using their own language, as a German, I can already see the "uh oh nazi" posts as soon as I'd write anything, whole communities will have no idea which server to join, and even if there will be "inofficial" language servers, that'd be much too late and obviously, newcomers won't know about that. That's not even considering there' still a LOT of people within the EU who are older and never learned English properly, or don't speak English well period. And even if they do, it's still a foreign language and most people will never feel as "at home" as MMO servers usually do.
It's not much of an issue in modern "single player" MMOs like ESO or FF, but if they really want to relight the feelings of classic WoW, it's a massive oversight to not add country-specific servers for EU.
