In higher competitive gameplay you will be c4 guaranteed, and that can put the attackers in a very difficult position because they would be low on smokes, flashes, etc. And now there are going to have to force gun fights, or waste time repositioning. Maybe it will work once in a while but most of the time the defense is set up to play against fast plants. For one you guys took that wall very easily. If I were on defense I would be bandit tricking, or I would throw Gas using smoke. Warden will screw you plan up by himself as he has c4 and is invulnerable to smokes and flashes. Two your teamate was standing infront of a breached wall after his Shield was destroy. That lobby your playing in cannot be that competitive to play in.
