I really like it. Played d2 alot and was disappointed by d3. That being said, I'm not a hardcore-minmaxing-perfect-endgame-build-player so I can't comment on this kind of endgame but I'm still having a blast running nightmare dungeons with my lvl78 necro.
There are still some QoL features missing, but imo the devs actually listen to the community and the patches they've rolled out so far are great.
I would say give it a try
