I don't understand that mindset. If I don't like a game, I don't have a desire to try to like it. I just play a game that I do like instead. I'm not saying that people that do feel like that are wrong or anything. It's just not something I get.
Personally I find the shooting in this game to be a really strong component. The visual and audio feedback and general feel make it fun to just shoot things. And while I think the PVP is an imbalanced mess, I'm still having fun with it (though it helps that I can go positive to 2+ KDR in the majority of my games)
It's all the stuff that surrounds the core of the game that I am just not feeling and has me struggling to log in.
There's marks to accumulate weekly, but until the Tuesday patch, I don't find Vanguard Tiger (or whatever the 24 one was) to be rewarding enough to spam, doubly so given my opinions on the game's current Strikes being bulletsponge borefests. My other option is to farm Public Events but I have zero interest in roaming around the barren open world waiting around for timers to pop. Crucible marks are whatever; I already said I enjoyed PVP so I can just let that accumulate in the background.
The game wants you to play daily but bounties and the daily heroic just doesn't do it for me. The lack of a true main city and player interaction has reduced the Tower to just be a bunch of service NPCs and vendors. There's no "living world" where it feels like you can pass the time just being social in the Tower, which IMO is a good reason to log in daily on top of the daily activities themselves.
There's material farming much like in other MMOs, but MMOs usually give me an option to get around this by just buying them off the auction house. Here, I have to partake in farming runs to get past 25. There's an argument to be made for doing it while hunting for Public Events or running Patrols but I honestly find the open world so poorly designed that I'm not compelled to engage with it. Of course, I stuck with Spirit Bloom and Helium Filament farming enough to get to 28 so I can comfortably do Nightfall and the raid but it just wasn't a good time lol.
I suppose the tldr version is that the shooting is good enough to make most of the game's activities bearable, but looking back the activities themselves feel pretty empty and have me questioning if I should do it again the next day or week. Of course this is all my opinion and I don't expect my logic to be sound or reasonable but yeah. And if it sounds like I want the game to slant more heavily into the MMO side, that's probably true too. Destiny has such a strong core to it but a lot of the parts surrounding it just don't work well.
