Legendary Items to only drop what they are classified as... Which means Primary engrams would never turn into shards etc. Less Special ammo boxes in all crucible maps. There's too much. All special weapons are basically one hit machines and since there is an unlimited supply of it we have what we have in the crucible (which is a disaster area). Faction Wars... PvP style faction game modes, and in PvE make a mini game so to speak out of all the territories on the planets and the moon. Factions basically partake in faction bounties and faction patrol for control of a territory. At the end of each week or month or whatever you tally it up and the faction which controls the most zones on the planet takes it over. Planets controlled by each faction gain extra xp, rep, whatever else there is for the week. Did I mention specific faction bounties? The always mentioned vault space. I would actually allow players to access the vault from orbit, basically from their ship. I would have multiple pages of inventory for each category. Kind of like how Otto did the faction rep viewer with that drop down arrow button. I would add the Hive/vex Boomer as a Heavy weapon and the Fallen Tracker gun as a special weapon. The tracker will be like a 5 round burst weapon. Kind of like a homing pulse rifle, but of course it's a special weapon so ammo is much much more limited. I would run Queens Wrath and Iron Banner at the same time each month allowing players to chose which one they want to do, or both w/e. Third subclass stuff.
