Yea, the mass of camping (on both sides, I hate camping the humies doors as alien as much as camping base as human) is actually kind of killing the game for me.
Aliens complain about camping humans yet insist on sitting right outside the base waiting for someone to come out. I can't even count the number of times I tell my team to back off because I don't want to play "assault the campers" for half an hour. Unfortunately too many players get a huge boner over camping and it basically forces the humans do either camp or feed like crazy.
Yes, they can break through, sometimes a lot easier then they imagine, but it takes a group of skilled players working together to do so, and that's more rare then it should be.
Of course, on the other end, even a human team that's winning will rarely move far from base unless a few of their better players have allready done most of the work. If they would man up and attack instead of sitting at the end of some long hallway killing the rushing retard dretches, humans would find themselves winning a hell of a lot more often.
I could go on because it's a much more complicated issue then most people know. I won't though because I have better things to do but both sides need to tone down on camping. I won't say it's not a viable strategy at very specific times, but too many people use that excuse to sit around on a turret for half the game.
