No, you NEED money-earning skills because you have to change gear so often. The entire RNG loot system is Sven's baby despite being a mess in both DS1 and 2, and the absurd scaling means that your gear becomes obsolete within a level or two.
It's forgivable in ARPGs like Grim Dawn and Diablo because there are respawning monsters, but even in those games, there are build-defining equipment and sets (offhand, Uruboruuk's Raiment for necromancers, Dreeg's for poison/acid occultists, etc). The random itemization in DOS2 utterly destroys any concept of gearing up, unless getting +Two-Handed on One-Handed Gear is your thing.
Vendors should supplement your gear process, not overtake it entirely.
