I don't really know if this is the right place to post this but.
My ideas for destiny or what I would like to see:
PvP:
Hive survival - kinda like infection/flood in the halo series, where when you die you turn into a hive thrall and kill guardians and infect them.
Sparrow racing - nuff said XD.
Space wars - something like star wars battlefront 2 with the space combat.
Fallen Vs Hive - like hive survival except one team starts as a hive and one starts as the fallen, and of course at the start you will be a thrall or dreg and the kills you get you change into the higher rank of that race, thrall then acolyte then knight, dreg then vandal then captain.
PvE:
LFG - needs upgrading and maybe lf for Vog and eventually crota (as the time taken king comes out they would be considered "old content" and there forth it would be easer for new players and characters to get their light up).
Hubs - The Reef and The Tower both need a overhaul, as pretty as they are, they just feel... empty, even with players in it.
Collectibles - like ghost that you can find around the game Bungie can have new things to collect say for a weapon or armour or even a shader or emblem.
Public events - need more and tune up the current ones.
EvE:
EvE - please have more world interaction with the AI.
Events - there needs to be more PvE and PvP events besides Iron Banner and I think The Queens Wrath.
Weapons - more balance, shaders for maybe exotic weapons.
Armour - just some more tweaks and maybe get etheric light to be a tad bit easer to get.
Lore - MORE LORE!!! I love the lore in destiny and I would like to see more of it both in the form of missions and grimoire .
Bounty - more vanguard and pvp bounties.
These are just some of what I would like to see, comment down below for what you guys want
