I disagree that it’s “much better” than the original. Its character build and UI are better, combat mechanics are better, as are its graphics, but other than that I think basically every other aspect is inferior to the first game.
Which doesn’t make it a bad game, not at all. I’ve got close to 50 hours in with it so far, and created my 4th build yesterday morning, a Crusader (Unbroken + Goldpact). Dude tanks like a beast while the rest of the party cleans up.
