MMORPG are meant to have common areas for players to hang out. That is the biggest failure for this group of managers. This is not a sprite game, this is not a generic FPS, this is not a mobile game. This was sold as an FPS RPG.
Even if it means retrofitting the latest world locations they need to correct this oversight. This is also why I hate Portal since it takes community and choice out of the players hand.
I will admit that I never actively tried to find players to do activities with, but I loved running into randoms on patrol and pitching in with them to do public events or take down high value targets.
It is a part of the game that hooked me early on in Destiny. Even when you went into a destination solo, you always felt part of something bigger when other guardians were out there too.
