When the next season and map come out, the playerbase will rally to some degree. The question is, though, how much will it rally?
It depends on what exactly "season 2" ends up being.
If it is a business-as-usual type patch, with maybe a new character and map, that wipes vaults
and faction progress, it's finished. Sweats on their Discords and LFGs and premade stacks can coordinate and max their factions again in a week and go back to shooting fish in a barrel, but the normal player that took 3 months to maybe get a few factions up, seeing all the progress erased and having to run naked Rook again, is just not going to bother. The way it is set up right now, if you don't start grinding a season the same day it goes up, there's no point, and there is no incentive to do so either. Just don't wipe faction progress., it's already slow as fuck to raise.
Now, if they are putting effort on a relaunch-lite with major system overhauls, new content, the customizability that was promised, and combine it with a free weekend + discount + NOT RETARDED advertising campaign (ie. STOP SUCKING OFF STREAMERS) it could work. Compared to the launches of other recent multiplayer titles, they haven't added a single event, or meaningful update, or anything to rally a playerbase at all for a month, just blatantly obvious bugfixes, balance changes, and "experimental" testing queues. They obviously had zero content planned for post-launch support like they should, because this is a beta build forced to release early by Sony after a major shift during development, and it shows (Arachne having ONE story contract is hilarious).
I am being slightly optimistic because of those experimental changes being put online, having a clueless developer trying to fix a beta isn't great, but it's better than having it openly abandoned. Ideally a core team will remain and try to wrangle the game with a coherent vision while Bungie moves to Destiny 3 or whatever.
Also crucify Ziegler and stream it with Durandal commentating live.
