Just to clarify, I ignore a coaxial with max 7 dps that is completely negligible, because everyone would except for those trying to be remarkably nitpicky. The Panther's total of up to 25 AI DPS on the other hand is a significant enough factor to mention in comparisons as it can reliably be used to chase away lone squads.
May I suggested you choose your wording more carefully then because "absolutely no anti-infantry" and "negligible" are two completely different things.
In addition if the coaxial benefits (and I have not checked) from commander and the vet bonus it does not become that negligible anymore.
Panther total DPS might be close to 25 but only in an ideal scenario and if it "chasing" a "lone" squad it would be closer to 12.5 due to moving penalties.
In the end of the day if the "superiority" of the Panther comes from it's MGs, I suggest giving the FF/M36/SU-85 of one hull and one coaxial (where applicable) and rising their fuel price to 180 FU. Then Allied TD would come with the same MGs (pintle is an upgrade that cost MU) would have better gun then the Panther and the Panther would have more tenacity.
In plain words the performance of Panther's Mgs does not justify the superior in cost efficiency of allied TDs enjoy.
