It's all depends of how many people are playing the damn game.
I suspect it's a low number. The game can be a moderate success on xbox, but in pc it didn't click as well.Even more, I think it's a game lots of people left after the first month of play. So as I say, I think the number on pc has to be low.
Now divide that low number of concurrent players in between the number of data center regions. There are, how many, six regions? I'm not sure.
Now take that new number, and take only half of it, as the other half are people that are already playing a game in a full 6vs6 game, not searching in the lobby, They can't be accounted.
Now take the even smaller new number, and calculate 1%, as it seems that incredibly small proportion were the interested in CTF.
If there are, for example, 7500 concurrent players, the number of players searching for a CTF game or already playing a CTF game in a region could be as low as 6.
A server browser would help a bit, but don't think that's enough to reverse the trend of a dying multiplayer community that is more focused on TDM.
