A 4th class that functions like a healer or buffer, or a more warrior type class. A 4th subclass with a new elemental type to increase the variety, maybe ice/water/light/ soooomething. More weapon types, can be more gun types.melee weapons that utilize special ammo. Fix the hammer of Sol, it's horrible, no longer viable in PvP, give it back it's splash damage, decrease duration to balance that out maybe. More planets and regions in current planets. This is a future sci fi game, why are we still in the solar system? Nobody even likes mars. An actual story with engaging and emotional narrative for once? Taken king was getting there, but it hasn't compensated for the rough stale start of year one. Like literally, Earth is -blam!-ed and I just got revived to kill some shit with vague explanation. Also you killed off interesting characters such as the queen and queens brother as if we were supposed to have developed some sort of connection with them. Felt nothing. More game modes, maybe even infection! Glamour system. Some of the new armour is undisirable to some. Emotes with voice in it, gives more life to our characters. Character recostumization. A lot of people regret our character choices and would like to change our looks. Also more features for our characters . For the love of god better RNG. Add hellish modes for older raids. Don't let them rott. New maps and more strikes. Better rewards as well. Long list of things but honestly I feel as if a lot of what I said can really enhance this game. I love Destiny and I Destiny 2 can do better with the potential it has.
