G-Cat, your servers are bland and boring. It's not fun to have everyone spread out across an entire GSF map, it just gets rid of the idea of actual combat.
What I suggest (this is only a suggestion, not a command, so don't go apestuff) is that you take a smaller part of a GSF map,such as one of the cities of San Andreas, close it in somehow (like fences at every road and a concrete wall around the city) and keep the fight in one smaller area. That way, you still get urban combat without having to waste fifteen minutes looking for anything to shoot at.
And don't say "lol but we have vehicles to use". You know just as well as I that those only are three one-time use things, assuming they already know where the enemies are.
