I think the number of French and English is still around even, I remember both were arguing in beta/early access for control in Mor Dhona...

I don't think the majority of our French players do speak very good English though. I know my French neighbours in Mist have players who cannot speak any English, which is why it's been a pain asking them to stop harassing members crafting near the market board. I believe you'll find French and English arguing on any server, to be fair. I've entered duties myself where I've seen a French player confused themselves at how other French players wish to play the game, and there's a French player in my Linkshell who was often insulting other French and their gameplay style.
