Your strategy sounds plausible, but is not IMO. As Cat said, "divide and conquer"...any attempt to group together as a team and focus on one target at a time leaves you vulnerable to any competent team. They will surround you, rocket-pop you out of position...group together too close, and you will be slaughtered, "fish in a barrel" style.
Not trying to be negative here, just giving you some counter-points. I'm not a good CA player...just to dispel the ego arguments

well yes of course youre right about the fact that it is difficult to start a round with perfect t4 style positionning etc
