I loved the beta, and I know it's NOT the final iteration of the game. I just have a few wishes and ideas that I think will make the game a tiny bit better.
Trading; Alot of controversy, but well that's why people are all different. I believe this will benefit the game and create a living breathing social economy. It's proven that MMO's with economy tend to get a more dedicated attached following. People will gets attached to there vaults and characters if they invest. Just my opinion.
Time Based Events; This will be a little more difficult since there's a bunch of people on different Timezones in the same game. I'm think a in game clock (different measurement of Time or no seen measurement) they could use the same implementation as Minecraft or fable. A Sun and Moon with a dial rotating in Destiny Time. They could also take the GTA approach and just make up a time and use that for the rest of the games lifetime. For the events I'm not looking for anything Major or really sociable, just a simple element to keep us feeling like the world is breathing. More "Dark" enemies (Witches/Hive/Knights/Ogres) can spawn at night with a +1 or +2 level boost. Different public event specified for night can also appear (Suppress the darkness from overtaking the land) etc.
Traveling Merchants; Specific Merchants can be specified for different worlds (most merchants probably wouldn't have space ship amirite?) And can wander randomly during the day. Rest in empty loot caves at night. They'll see items at a higher price, they'll rarely contain rares, but will always contain the ammo packs. Access the Vault via transmitter. They'll also let you see your current Vanguard, Crucible, and DeEncryption rank (forgot what it's called) so they'll be useful but not miracle workers. You'll still need the tower for most things. They'll also get a a refresh more often (every hour) and despite them walking they'll still teleport to a random location on the planet they're assigned to every half hour. This prevent people camping the Merchant for loot and ammo. Restricted from dungeons and tend to stay away from mobs.
Fireteam Instance PvP; This is self explanatory and I would LOVE to have some type of desperately ranked mini game. In explore you'll be able to challenge other Fireteams of similar size to a PvP match on the spot. Soft Boundaries would pop up and you would be thrown into your own "instance" (similar to when players on a story mission disappear from other players view when entering No Respawn Zones so they can fight the waves as a Fireteam/solo) to fight to 25 or 30 kills. This will make a more seamless action in explore. You won't be able to launch in certain Areas (indoors, dungeons, and raid areas) and all Fireteam members will have to accept launched by targeting another member of fireteam and viewing the options.
Weather; Only if it doesn't affect performance. Weather is hard to add into a detailed online game since it's very graphic intensive. If it doesn't affect gameplay it can be a good way to add an additional element.
Traveling NPC Quest; Similar to traveling merchants they'll travel around and give you slightly harder version of the beacon quest. Kill this many of these monsters, Collect these items, etc. They'll teleport every 15 minutes and you won't need to return to them upon completion. These will actually be redeemed on the spot (similar to Beacon Missions) but since there will only be a few on every planet, they'll be more more vanguard points (15 to 40 Vanguard Points) and will be used in conjunction with the Beacon missions which will remain the same with Vanguard Point awards. You can only talk to each questgiver once per hour.
