Nope, the question is: are we allowed to play on the German servers?
A) Yes, so the Cpts have to agree on where play the match, whit the possibility to chose between France and Germany
B) No, the German servers are too laggy. But this option have to be said by Herishey, who is the leader of the tournament.
Actually we are in the A situation, so you can't say "France will play JUST in the French servers" because you have to keep in mind the opinion of the teams you will face. If someone want to play in the German servers you will have to deal with it. Moreover, saying that you won't play on the Germans servers unless an admin imposition, you are also stopping the possibilities of dialogues with the other Nations.
So, yes Melton, it is up to the Cpts, but a nation can't refuse totally to play on a server, not even considering the opponents' condition.
