The way you get Bungie to make good, solid, lasting change is to make them internalize that the design strategies are undertaken this year were wrong. The only way, the only way to do this is to leave a permanent mark on their fiscal year numbers. Not by filling a subreddit with negative topics, nor tweeting your disapproval, nor making angry Youtube videos about the state of the game. Real lasting change is only ever about the money. If a company takes a big hit to their finances in a given year it informs every decision they make for subsequent years. It tars strategies taken in that year as Bad Ideas forever.
If enough current players don’t do this, even if year 4 is a turnaround, it will do entirely the opposite – it will entrench the notion of a year like Y3 as a Good Idea. Bungie will instead take away the knowledge that they can run a Phone It In strat for an entire year to cut expenses and draw more income from the real money store and it will not hurt their bottom line enough to be significant, and if they just put in a bit more effort and say sorry at the end, everyone comes back. That will mean a lot of years like this for subsequent games.
