I've had DMs that abused command. For example a DM that hated players wearing heavy armor was running a game on a ship (this was an AL equivalent game, not a sailing campaign). He had an NPC command my PC to jump and then told me that it was obvious that I should jump off the side of the ship. Instead of ... I don't know ... jump straight up, jump onto some other part of the ship, jump into his arms ... pretty much anything else. Nope, I had to jump off the side of the ship where of course I sunk like a rock.
So I don't have a problem with clear limitations and results for a first level spell. A lot of people avoid it because it's so vague.
