The original Destiny featured such robust social features as poorly managed chat options and a total dearth of social features to help people form groups. This wound up finding a great deal of acceptance on consoles, because console players are accustomed to developers treating basic MMO functionality the same way that 12-year-old boys treat romance scenes. However, here on the PC we don’t take that kind of crap, and Destiny 2 players are taking to the (metaphorical) streets demanding things like LFG chat, global chat channels, and in-game guild chat.
If you haven’t been playing the game, it might baffle you that an MMO could release in 2017 without these features, but here we are. The discussions are fairly heated on both the official forums and Reddit, but largely in favor of such systems (with several snarky comments about how in-game friendships are based around barely talking to other people), so it remains to be seen whether or not Destiny 2 is prepared to handle the influx of demands by MMO players.
Meanwhile, Bungie announced today that Curse of Osiris will release on December 5th.
