I'm glad I'm not the only one who feels this way. I have tried coming back to the game multiple times and every time I just feel bored and underwhelmed by the whole experience.

Yeah...I played it for probably a couple of hundred hours...and it wasn't that fun. In fact, it's boring. And I've come back a too many times because someone (like some of the commenters here) said "no, man...get the new update! It's a Totally Different Game!". So I jump back in, and it's different to varying degrees...and still boring. Just because there's "lots to do! new quests! rare items to find!", doesn't mean doing them is fun.
