As said previously, the summer is our peak, and we are entering a slow period right now.
Also said above, many of us only play certain game types.
My BF2 account has over 1200 hours on it, and i find it difficult to play conquest for more than a few rounds as a result. I will play for longer if there is a fun group on vent and i'm having some laughs.
I also have a tendancy to leave our servers if there is no one in vent, or the only players on are in a locked/leadership channel. I'm a social gamer, I like to chat in vent and its a shame that more of our members don't automatically join our vent channel before logging in.
It could also be useful if we had a more organized system for getting people together for starting servers.
I like the idea of a potential steam group or friends list, allowing Duality/noxx/music to message the members online to show up for a limited period and kick off a server. When I played Bf2 we used a similar system and it worked very well. Even busy people doing homework can often spare 15-30 mins to starts a server. At least I found it easy to do when i was in college, and it often proved to be a good break.
Just my thoughts
