NPCs in patrol zones instead of lifeless beacons to give out missions other than scans or collections. If you've played an elder scrolls game you're familiar with this approach. More dialogue with NPCs. Most of the dialogue is limited, even with the vanguard, who could be used for much more than gear vendors. I mean Ikora, a character with massive background! Is literally a run of the mill vendor with gear you'll forget about after picking up your raid gear. People to actually protect. You're a guardian, humanity's last hope and protector, I've never felt like there was something I was protecting. Add a mission in the city or a game mode where you protect a camp or group or travelers or a lost group of people or I don't know ANYTHING. You remember firefight! Make a defense game mode where you defend a position against waves of enemies. The location could be outside the city or an important structure on a planet. Let me know what you think about these ideas and feel free to comment with your own. I know I'm not the first to come up with these but it's nice to get eyes on stuff like this!
