I just tested the Pontikoi Thorakitai in a custom battle against sThureophoroi and I have to say: Oh my god! On even ground, the Pontikoi Thorakitai got slaughtered down to 17 men before running, and 78 of the enemys Thureophoroi survivied the slaughter. This was on large unit size. I mean, that really must be unintentionally. According to the Pontikoi Thorakitais' description, Thureophoroi are supposed to guard their flanks and provide them with flexibility, but as it is now the Thureophoroi do the Thorakitais job even better.
