Have you checked out the builds on icyveins? The synergies on some of them, like the earthen bulwark build for example, are kinda crazy. Definitely more diversity than I would expect of a single ARPG class but then I got more into the game as I heard D4 going more MMO-like so that could just be me.
I have yeah, it that’s kind of the problem - it’s icyveins or bust unfortunately. I did go pulverize bear which made it better, but I had the same experience with d2r.
I guess I just hate limits, I like in poe….if I want my toon to do something specific (such as fast cast speed) I can spec into that and work on it. Where as Diablo….I might get 3 passive points 😄
Chalk and cheese though; D4 did good with getting the masses to enjoy a venerable entry into the genre.
