BG3 possibly fixed this problem for me. It not only throws scrolls and potions at you at every corner, especially later on the fights can be significantly harder than they need to be if you don't use those consumables. Physical resistance in stronger enemies literally halves the damage you do and using an oil reverts that. And when a boss can one-hit kill with a fire attack maybe that fire resistance item doesn't look so uninteresting anymore. Use consumables and long rest often in this game, your experience will certainly be more enjoyable.
