Thank you for your feedback.
My reasoning is that there were (arguably) only a couple maps that were big enough to hold 64 players. If they want that many players to fit onto a map they should have more than 4-5 flags - just think that means to win (by controlling 3/5 flags in order to make the opponent's tickets go down automatically) you can have 10-11 people at each flag defending (assuming you have a team of people working together and not almost everyone running around like chickens with their heads cut off). And rush is near-impossible to play as an attacker with 64 players, and 32 can be difficult enough when you only have to defend two points.
