Apologies if I'm being thick, but, why do the overall subscriber numbers affect whether or not one feels they should be resubscribing? I enjoy the game and so long as I continue to enjoy the game I will resubscribe. If I feel that the server I am on is too quiet, I'll roll on a different server - though this is unlikely as I'm in a guild of people that I've been gaming with for several years.
Enough of the doomsaying! Enjoy the game? Then play it!
