Hey there @Majaxable!
Sorry to hear you're having issues with your ping - good news though, we are already looking into this! And regarding our servers, @SereneSl0th posted a list in this thread.
Also, you are right. At the moment, there are no dedicated language forums for Rocket Arena (yet) but we are open to reviewing this again in the future! Je suis désolée - my French is too rusty to reply in your native language but you can always post on our French board if you are more comfortable doing that, and your questions will be answered there.
This applies to all other languages that we are supporting here on Answers HQ, too, of course.
