I agree with you and have had similar experiences. That said, the difference is that I'm not disappointed. I realized early on the this game was not an ideal fit for my gaming style (prefer solo) or my lifestyle (kids, marriage, career) and it would limit my full experience. As a result, I just decided to enjoy the content I could readily play, got good enough to play more content solo, but never pouring countless hours or feeling compelled to be max light on end game coop modes. Destiny as a game is not a great fit for me, and I'm ok with that.
