So. I set up my elgato and ran some tests on panther vs comet for the sake of perspective.

I have found at vet 0 comets lose to okw panthers 6/10 times 1v1, at vet 2 comets lose to panthers 7/8 times 1v1 and at max vet okw panthers win their 1v1 engagements against max vet comets a 100% of the time (sample of 2).
That's heads up and some of the engagments were a lot closer than expected. Comets also have great mobility and the accuracy on the move is much better than the panthers. Panthers blitz abilities have not been accounted for. These tests are in a vacuum and when the rest of the faction is added the winner of the engagement is most likely to be the better supported tank.
It's also worth noting that comets vet much faster due to their generalist damage profile.
To me, it's less about performance and more about cost. I don't care how something performs as long as it's cost is in line. For example, I would like to see the cost of the OKW AAHT come down around 25-30 fuel so that it's vulnerability is accounted for in it's price and it's not always a losing purchase. I would also like to see the cost of OH panther brought down to 150 fuel and the OKW panther brought down to 175 fuel and have the stats left alone. Or give the panther's Vet 2 armour and health increase back to it's Vet 0, like it was originally and adjust the cost upwards to reflect this.
