I agree at least that casters need far more options, especially wizards and priests who lack passive abilities altogether. These classes feel like they are only half a class and playing one without multiclassing just feels... underwhelming, boring even. One of the things I loved most about casters in PoE1 was that they had so many tools available to them from the get-go, that they felt like they could contribute in any situation. I also liked that casters played and progressed differently than non-casters, reaching that point where you unlock a new spell level was satisfying in a way that just doesn't translate into the current ability tree. Every level up feels lackluster in comparison.
