I have no problem with these "tactics" on maps such as Arachind, where there are enough places to devise tactics; but come on; ATCS? What tactic is there that takes 10 minutes to get ready on ATCS? Aliens dont need a base there so long as they make a quick rush and get to the nodes. And on humans; I mean; come on. You need 3 minutes to get a base there; five at the max. And you certainly do not have to worry about repairing when aliens are dretches.
There was, however, one very memorable moment when we were playing humans; Seldom was coming intoour base from the hall and jumped down to avoid fire, the thing is, he didn't notice we kept the two turrets down there; scared his shitless, Goons don't normally make faces, but god, he did that time. Priceless. He immediately pounced back up, of course.
