My suggestion is to give players the option to reload more missions immediately after they complete their current 3. Yes, I understand SD reloads them every 3 hours to get people to play more throughout the day which is a good idea. But there are different ways they can do this that can involve people playing together longer in one play session AND/OR playing more throughout the day.
Examples include:
*Maybe if a person chooses to reload 3 new missions they can get a reduction in credits earned…So maybe instead of earning 500 credits they may earn only 400.
*Maybe only allow a person to reload a certain amount of missions within a certain time limit. So if a person reloads 3 or 6 new missions within a play session, then more missions won’t reload within the next 12 hours
The reason would be to increase player time in the servers. I notice a lot of times people play 1 or 2 games to earn their missions then leave. So people often may not play long which reduces people playing together. So maybe if people are currently having fun with the people they are playing with, they may not leave only to earn more credits in the next 3 hours. I have done this a lot in the past as well only to play again in the next 3 hours.
There can be many ways for SD to implement this. I really think this is a good idea, hopefully I was able to make my point clearly.
