With expanding haven i dont mean making it bigger, but with having more things in haven to interact with. Like make the missions only available by talking to NPC's first. This will give the feeling of the missions having an actual story and it should give a little break in the pretty repetitive Mission gameplay. Also, because at the moment you can pretty much finish the whole game without even coming out of your ready room. Another thing is instead of these crossed swords in the top-right corner of the screen (where you start Pvp). You have an elevator where you have to step on to join your PvP game. When you step on the elevator, you get into the waiting room, where you can have a little chat with your possible fellow teammates until you find a game. Also maybe that you have to start the danger missions at an Npc? As them more being side missions.
