I just had a blast playing in the LW arena. The reason: Tank town was up.
I was the 349 of 350 to log on. I'd have been just as happy driving my panzer in MW, as I suspect lots of other folks would have been. In fact, the one time that I logged in and found big numbers in MW (my personal fave) was when the tank town map was up.
So my suggestion is that we reserve the really fun maps (those with TT and FT) for the MW, which for some reason seems to have anemic numbers. At least until others see the MW light.
This way guys who want to furball or GV always have a place to go while also freeing up slots in LW for guys who want to fly in there.
