i think they were very good snipers with very good teamwork and they definetly had a great tactic if it was a tactic i dunno but they came out a little weak whilst keeping there score below but as close as possible near ours so when they took position for like the 3th time they kept it and started playing for real and thats how they had a 700 points advance at the end cuz they first saw our tactics and our way of sniping and then they adapted to it.
its a nice strategy which i used to use but dangerously if the teams have equal skills or you underestimated the enemy or yourself.
