I mean they now added so every new game starts you of selecting up to 3 starting ops. So if they make it 4 you can probably play the campaign with friends. I hope they consider this because campaign mode is the bread and butter of the game.
Like encourage stealth and to neutralize the captains before they call for reinforcements? Maybe reinforcements is infinite and your team will need to hurry and finish the mission else they will insta arrest the group's ops due to them being overwhelmed should they have their cover blown.
