Replace the DMC with an AMC or ST.. I play hexagon and have been scoring at an average of exactly 3 in league. 4-5-1 v is very defensive... You should play normal/defensive and force counter. Also when playing counters pass long, since you don't do it in triangles. And of course, experiment with the orders. With defensive and counterattacking formations high pressing doesn't suit, since what's the use to counter if you go high up the field?
