Oh, so is it set to battle all of the time now?
Edit: Also, I notice that POM seems to run battle-mode full time and that people seem to go there before your battle server. I don't see any populated NA siege servers anymore. I tried to play another battle today, but honestly I just don't have the patience for it. People tend to turtle up and then eventually individual players will tire of the wait and charge a group and usually die due to being outnumbered. It just all seems very boring to me and, like I said before, if you get picked off early you're forced to either watch the remainder of the match, look for another server, or just exit the game.
I'm at the point where I am shelving Warband due to the lack of a NA siege server. I know you took a poll on this and the numbers are pretty even for both siege and battle modes, but I think people on the forums are more likely to vote for battle because they are in clans and are using voice communication. I would venture a guess that the majority of the casual or clanless gamers, like me, prefer either duel, TDM, or siege servers. You just don't hear many of their voices because they aren't as involved with the forums. Anyway, I suspect that if all there is available are battle servers then the NA population will continue to slowly die.
By the way, I'm not trying to convince you to change the mode to siege. Your clan seems happy with the present situation. And you guys are paying for it, so who am I to argue? I'm just trying to show the perspective of the casual and clanless players out there and why they aren't lined up to play your battle server. The few times I did play, when the server was set to siege mode, the numbers were pretty good at 60+ every time. I'm sure you know the overall numbers better than me, but from what I saw siege was much more popular. But, on the plus side, you can probably get a smaller (and cheaper) server if you go battles full time =p
