Only if your definition for "HD", as it relates to TV antennas, is "Highly Directional" in which case you'd be the only one using that definition. Everyone else assumes the marketing departments in all the antenna companies intended it to refer to "High Definition", a usage only a marketer can love since it drives the technical folks nuts. In reality, any antenna no matter how well or how poorly it performs, can be called an "HD" antenna if it happens to pick up "HDTV". Kind of like in the old days when antennas were labeled as "Color TV" antennas, same antennas, new boxes or labels.
Due to the combination of distance and signal spread, an antenna that is "too" directional might indeed force the usage of a rotor. A less directional combo antenna aimed so it splits the signal path, is probably a better option if the hassle of a rotor is to be avoided. Since there's no such thing as a free lunch, either with antennas or in life, the ill effects of multi-path are more likely to be encountered with the less directional antenna.
Some experimentation is likely to be needed, but a "medium-range" antenna that covers channels 7-51 (or wider) would be suggested for your full-power stations from DC and BMI to see if that rotor can be eliminated.
