So I had an idea for a huge event that could happen, and it came to me from the battle of the Twilight Gap. So around the time Comet (1.5) comes out, we could have the Hive attempting what they've been planning since we found them on Earth, a full scale invasion. Have the Hive attacking the city and we, as guardians, need to defend it. We could capture control points, kill enemies, and take back parts of the city. Make it an open world, timed event. The whole thing could last a week, with a different objective each day and an award for people who play every day. We could build on lore and have different high profile guardians leading the attack,, like Shax, Saladin and the Vanguards. It could play out really interestingly and would be a major part of the world building this game so desperately needs. Also, and this is just an aside, Bungie could use it to introduce new vehicles and siege weapons for players to get accustomed to. Let me know what you guys think or if you have an ideas to add
