The three laziest aspects of Elite: Dangerous.
1. Unidentified Signal Sources. For a random event mechanic, they are surprisingly dull and disappointing. After the first ten or so, I never went to an unidentified signal source again looking forward to it. I would say they need more events, but I chalk it up more to bad luck on my part. However, the majority of events are really not worth the time it takes to actually check out the signal. To me, it feels like they are specifically designed for padding certain missions.
2. NPC AI for docking. As far as I am aware, they are not aware players even exist when docking. On top of that, they have a habit of breaking around docks. I remember in particular multiple times where an NPC was stuck rubbing against a part of the station. I am not saying necessarily make them perfect, just... try to give them an awareness of nearby players. I can't tell how many times a sidewinder has died to me, or a type-9 has idled in the mail slot. (I did confirm they were NPCs.)
3. Asteroid belts. I'm not sure this counts as lazy, but I have never, ever felt like anything good came from an asteroid belt. They are useless for mining compared to planetary rings. They are practically useless for exploration, both for Credit gain and interesting aspects. They have nothing to do with trading of course. Nobody goes to an asteroid belt for combat, as far as I've heard. To top it all off, they are separated into clusters, which are a headache to deal with if you do go mining or exploring involving them.
Add content, any content, to asteroid belts to make them worth my time. Maybe add unknown outposts, or make pirate missions sometimes lead to them instead of USS, or really anything at all. I'll take SPACE MOLD if you make it have interesting colors and shapes.
