I don't know what your talking about because his statement is totally wrong. Each map is little more or less fun than others. And a few are allot more fun and a few are allot less fun.
I know that if I spawn into a camp I'm not coming back. Of course I think I'm a little bit on the smart side. Of course I know this just ruins YOUR fun but it doesn't have anything to do with the map, I just don't like getting killed before I can fire up the engine.
Maybe more people are smarting up and are getting better at avoiding the spawn camps. Maybe they are getting better at busting them. I've had fun GV fights on all the maps, and I've run into nothing but spawn camps on on the maps.
It's the people, not the maps.
