That the AvA has lots of dogfighting despite the low numbers speaks to the kind of players they are and not their numbers.
Perhaps. I just know when I've been in there 6, maybe 8, is a large group. If someone does try to grab a base, sometimes the arena is set so it can be near impossible for just one or two guys to grab a base.
I've seen v bases flashing and gone to defend the base. Usually, if I kill the aggressor, that's the end of it. They go back to dogfights, or log off.
But, I suppose the majority of players there prefer dogfights.
