The utility of cantrips is certainly modified by DM style, by campaign design, etc.... I didn't call it out because I know my experience is a bit different than others, but Mold Earth has been A tier for me. When setting up defenses it has allowed us to create walls and trenches. It allowed us to burrow through some dungeon areas. It allowed us to bury things quickly and recover them later. We've buried enemies alive with it (dig a 5 foot wide and 10 foot deep hole with it (requires 3 castings), get an enemy in the hole, cast once more to move dirt on top of them. I even have a PC that runs a construction business between adventures using cantrips, rituals and a few non-ritual spells ... he can build buildings in just a few days and this is a key spell in that process. However, I know a lot of the use cases I saw were DM and setting specific interpretations and options. 'Loose Earth' is going to be interpreted differently by different DMs. Jeremy Crawford once said, "think dirt, not stone." Some DMs think it is only useful in a field that has been recently plowed. Approaches differ. However, it was amazing for me, historically, with a wide variety of DMs - but rarely is appreciated by others. Ot seems like your experience with Resistance is like mine with Mold Earth - you have seen far more utility for it than the vast majority have.
