With cloaking, that is.
Why do so many people complain that cloaking takes the fun out of NS and that an invisible enemy sucks?
I think people should amend the statement "cloaking takes the fun out of NS" and change it to "cloaking takes the fun out of NS for rambos and stupid commanders". Teamwork and smart commanding can easily counter sensory, assuming your marines are halfway competent.
RAHHH!!! BUFF SKULKS!
