Welcome back! Im sorry to say the glory days of 600, even 300 players on at a time are gone. At the time of this post we have 138 in the MA right now.
Bad news is the numbers ARE down. Good news is you can still fight the type of fighting you like. The problem is that that type of fun is spread out time wise. Some times of days the base takers rule, other times its furballer, other times its strat runners.
The game is still the great game it always was but with the numbers being much lower the "lame" game play seems to stand out more. In the old days you might find a bunch of HOers and runners. You move to another section of the map and you could find a fight more to your liking. Today not so much. With a 6 hour switch side limit jumpin sides doesnt help the issue much either.
