There’s a difference between spawn camping and ‘tactically waiting’. Technically, the CT’s shouldn’t be pushing, its their job to guard the bomb sites, not rush, thats the T’s job. If and when the CT’s push out of A halls, I’m all for camping somewhere with a rifle and shooting them. In a way you’re just watching the flank.
Same goes for D2, inferno, nuke, etc. But if they don’t rush and your team is decimated, you’re camping spawn. Especially if you’re just hiding behind something waiting to *edited* someone running by.
