My character's Soldier background actually proved useful in the adventure my party is currently in. Baldur's Gate: Descent into Avernus. He was the only member of the party who was proficient in driving a vehicle (a Demon Grinder). He's been driving his teammates all over Hell.They mad because people did not use backgrounds except for the skills. But I don't recall any adventure in which backgrounds were important. and only about 3 or 4 of the season modules which your back ground was of use.
