1, [b](Re)Grinding[/b] - Think a big reason why many players don't enjoy grinding anymore is because the game loop has been very stale & predictable for years on end from a macro perspective - if the game doesn't considerably update itself on a semi-regular basis, people get bored/tired of the same old same old and move onto the new freshness somewhere else... 2, [b]Serving the Audience/Quality of Content/Management[/b] - Reality is, Destiny doesn't cater it's audience, it has previously tried to extract the most from the least possible resources, relying on gimmicks and cheap burn content on average - seasons/episodes are at a very poor quality and the team isn't agile enough to shift development at a fast enough pace due to poor management, institutional bloat and a of lack of overarching vision. I like Tyson Green and think their vision for the game is what's been needed for a long time, If this can be executed and at a pace that can retain/grow players remains to be seen. 3, [b]PR & Trust[/b] - As much as I like Destiny 2 for some things, Bungie has destroyed a significant part of their own fanbase. Goodwill and trust is sorely lacking, to the point many want to see Bungie fail due to the volume of their mistakes & perceived arrogance - Bungie is not a likeable company, as much as some might think this doesn't matter, it often has a large impact on overall game sales and marketing.
