The thing you have to remember is that a huge chunk of people that invest in the game will play it for Multiplayer, Campaign, or, if available, Zombies/Extinction. A very small amount of those players will play for Squads/Survival. So, while they may be fun, they're certainly not successful in terms of people playing en masse.
