I've played Destiny 2 religiously throughout Warmind up to Shadowkeep, but after giving it some thought, I feel like I agree with you. Most of the fun I've had in that game was because I played it with my friends. We were happy messing around and shooting at each other's backsides and maybe occasionally getting something done in the scarce 3-player content there was, kind of like a glorified hangout space, but if I had to play it by myself? I don't know, chief. I do love the feel of the guns and the lore (up to a certain point), but I wouldn't call the game itself a good time.
