It's no secret Destiny 2 has a lot to work on to make itself the game Bungie promised. Recently they announced to be working on the weapons system and how to fix it after being asked by players to revert to the previous system that D1 used.
Destiny 2 seems to be a dying game with it's community leaving in boatloads. Bungie are attempting to improve the game and restore it to the level of respect players have for the original Destiny post-Taken King. They plan to tackle the issues of weapons this time around, stating it might have been a mistake to make this new system like this.
What differentiates the current weapon system in D2 from the one in D1 is the change from Primary, Secondary and Heavy into the new Kinetic, Energy and Power weapon slots the players will equip respective weapons into. This system did provide more variety for the weapons but users found troubles with the impact of the weapons.
Bungie responded by saying the players are making a valid argument, but while it would be the easiest to just revert to Primary, Secondary and Heavy weapons, they want to make a newer and more improved system which will please players and hopefully bring back some of the Destiny glory.
So far it seems like all they have been doing is reverting to what Destiny 1 currently is. Sadly, Destiny 2 is an empty game, to the point that players compare it to D1 and say that D1 is magnificent in comparison.
The audience isn't happy with how Bungie are treating them and how they're treating the franchise. It feels like there is no communication in Bungie between co-workers, let alone communication between Bungie themselves as a whole and the community that plays their games.
Bungie keep promising more and delivering less, sometimes not even delivering. The fans have noticed that and it's only a matter of time before the game dwindles to mere thousands or hundreds of players, after which they will be announcing the next expansion or the next installment and it will be like everybody forgot what they've done with D2.
