Most of the uses I have found for dynamic blocks as point symbols in LDD were related to drawing cleanup. The ability to move text independently of a symbol, stretch a guy anchor to a utility pole, change a single pole sign symbol to a double pole symbol were pretty useful.
Because of the dynamic limitation in C3D, we changed all of our symbols so that we didn’t have to mess with exploding and reinserting points just to get the dynamic functionality. Even without the text beside the symbols it is still difficult to show some areas due to overlaps with the symbology itself.
