I think I've nailed down what my only serious problem with PHR as a faction in Dropzone Commander is... their dropships.
Now, I know the PHR theme is slow, good punch at long range, and high toughness. But, with PHR dropships the theme seems to have been deviated from. The difference in point cost (typically over-valued compared to the other factions), punch (virtually no real offensive power), and speed (or, more accurately, lack of speed) is a triple handicap, I think. Mitigating just one of these would really help them be less of an "uphill battle" type of faction.
