Do you have a link? what were the arguments for a large one, I'm interested.
I suspect that a bigger map per-say isn't the issue, its that the penalty for loosing a base, etc.. isn't great enough to encourage people to care.
i didn't go looking. it was kind of a serious question. i thought i had seen complaints of that before, but wasn't sure. i'm just finishing up my massively fun day at work here......
in the lw arenas, i don't know why no one bothers to defend. in mw, what i often see, is that whichever country may be close to winning, will ignore attackers, and continue to try to roll the bases of least resistance. they won't run from a fight....but they won't defend either.
sometimes it gets annoying, but i don't let stuff like that bother me anymore. i go bomb something. i go shoot guns on a vbase, and eventually someone comes in an aircraft to shoot at me........or i fly in the ava.
