Attackers should have more than 1 flag to begin with. I could have sworn that chadz specifically instructed people to give defenders at least 10 spawns and attackers at least 3. So why is it that defenders seem to have around 10 flags, but attackers still only have one? Either way, if the devs want to make it to where defenders spawn a minute before, the attackers need to spawn all at once initially. This much has at least been proven. Though I personally disagree with defenders spawning a minute early. It seems to be a waste of a minute that could be used for battle.
I'd really rather not see the flags go completely. They introduce tactics more complex than bring as many people as possible. Not only that, they can shorten the length of battles and avoid ruining scheduling
