I just played a quite decent game on [T]Base, map Transit, in the human team. At the beginning, we were painfully few, only 3 humans vs 4 aliens for a pretty long time, later, a few others joined, but it never were more than 20 people in both teams at any time, usually rather about 15. And there is a golden rule I even have a binding for yelling it at my team:
Don't leave the base undefended!
What shall I say? I keep to it. Obviously, with noone else releasing me from this duty, I was stuck in the base. So I kept repairing, building, moving structures into the relative safety of behind the big crates and: defending - we did have a goon visit from time to time, and usually, with so few people, a human base tends to be easy prey for you aliens, because people have a tendency not to keep to the golden rule mentioned above ... So, why not visiting and killing the human base? Because you have a real darling with a shotgun anticipating exactly what you are up to!
And it was just a matter of time when alien players would start to yell "campers, campers!", later, "jetcamper, jetcamper", just because I was fuzzling around with a construction kit or with a lasergun, not wasting ammo on tyrants, but picking advanced goons, and taking them down.
There is a difference between camping and defending, you know? And, believe it or not, I was the only one who was nearly always in the base. I only dared to go out two or three times in the very early stage of the game, taking down a goon, killing an egg, but never too far away from base. If I could have gone out, I would have, just to increase pressure on the alien team, but I couldn't. So I stayed. And - believe it or not - after a long time aliens keeping to spam eggs in that huge map, successfully dispersing human firepower over the whole map, they could not regroup, because all but me where constantly attacking. All but me - for at no time the human base was undefended. You always had "a real darling" in the base, knocking out attacking goons if possible, repairing all damages that could not be prevented, and later, even running around in a chainsuit, but switching back to laserjet, because advanced dragoons proved to be a much more serious threat to our base than tyrants.
I realize that some alien players got pissed, because they could not get in a comfortable position to snipe (or even do worse things), for there always was this nasty guy around firing at them, high above the ground, where tyrants could not harm him, keeping to one and the same target [another golden rule, btw] until it either got out of range - or down.
I agree that is not funny not to succeed in heroically bringing the enemy base down all alone, I agree that it is not funny that certain sneak-attacks don't work because you have this guy anticapiting them, but, believe it or not: This is the idea of defense, and I implemented it faithfully.
We won the game.
And if it hadn't be for me, we wouldn't have, despite the skills of the attackers. And next time, take a thought or two about the difference between defense - and camp.
