Agree, but a good CQ map always allows you to attack 2 other flags, and formed as a circle as you mention. We have seen too few of those maps.
And those we have seen in BF1have been flat and uninspiring, as if they were made fast to satisfy CQ players.
DICE used to be good at making CQ maps that did not collect 64 players around 2 flags, but they changed their focus due to operation.
