Insight from more senior players

So I've played Diablo 3 pretty much since it has come out on and off, I'm trying to get back into it but replaying through the story is so monotonous and is just bland to me. My builds continually make it easy to go through without much strain and things like the seasonal and what not escape me as to why bother? The hellfires are super easy to get now and to me overall, there's no end game to really enjoy. 99% is just farming for better gear to be able to work up to like Torment 10 and when you hit that, what's the point? Rifts are great farming, basically the only reason for them. If someone could give me some inspiration to get back into it that would be awesome. Thanks!
