Before I start I need to underline that is NOT a nation-bashing thread, so I won't name the countries that mostly seem to be involved.
There are a number of large EU realms that are changing for sometime now. They are listed as English realms but are for some years now slowly overtaken by non-English speaking players, that form their on guilds and also chat in the Trade channel in their own language(s), more and more.
My own realm has reached a point where people are starting to feel... lost? Maybe even stressed or angry at this happening.
It's getting harder to interact with other people that either don't want to speak English, or (even worse) perhaps can't even understand it all.
Are you seeing this on your realm as well? What's the impact of it on the experience on your realm?
