I too was disappointed with how that played out.
The 'D-Day' map was the first map used, and was abandoned within 2 minutes because, quite rightly, it was terrible. The attackers lost their powder charges as soon as they jumped into the water. It was like shooting rats in a barrel for the defenders. It was a real uphill struggle to convince the admins to even change it, I recall several admin messages saying 'It's only a bit of fun'. No, it's fun for the defenders. Not the attackers.
So after that, we managed to get in a good two rounds with French attacking for 2 rounds, British for one. Slight map change on the last round, but it still remained balanced. Then, for some reason I can't fathom, the admins decided to change it back to the D-Day map despite the fact that it was 2-1 to the French, so the British could still force a draw.
The Admins polled the server, asking 'Would people like to play the D-Day map next?' (Paraphrased). 90% of the server responses were a solid No. Map change anyway! Surprise surprise, British are now the defenders, LOLing hard as we once again have to attack on that ****ty map. A real ****ing shame that the night had to end that way. Everyone was enjoying themselves playing on the previous two (balanced) fort maps. I quit early, too disappointed.
