I agree with Baalz 100%. This is what I am seeing in the games I play in, but then again I am not playing the aggressive facehugger in more than one.

I one of the games I even have something as rare as really trustworthy ally whom is helping me with everything I want to do. I only "gained" him because I invested time and a lot of resources in showing that I can be trusted when the enemy is knocking at his gates.
But of course you must be vary of signs that indicate that he is turning against you - as it will happen eventually anyway.
It is a fine line between trust and mistrust; and walking this line is actually something that I believe you must master to be able to do well in many MP games.
