Firstly a jackon is not a tank. Its a dedicated tank destroyer, its not capable of doing anything else unlike the panther.
Names don't matter much. What matters is that Jackson is realatively cheap and doesn't require any repair unit. It has a turret, is very fast, and has the range of an ati tank gun. All the above combined makes it lethal and unlikely to absorb fire.
The price difference should make panther a better vehicle. Panther has better armour and more health. In reality these advantages are easily outweighted by the range and potency of Jackson's gun, and the crew. So you pay less for Jackson and get the same or even more. Panther to be fully operational needs another unit to follow it and repair. This means that you need another 200-300mp more to make it operational. Add 100+ manpower 40 fuel cost difference plus more tech required and it means USF can field another elite infantry squad plus have some manpower in a bank in the meantime, or get a bit more fuel and have another tank! It is really unbalanced.
Panther is ai capable. Panther is more durable. Panther has blitz to escape or dive, and heavy crush. But it has shorter range. And nothing like hvap.
Panther ai capability is very low plus you need to pay extra 60muni for it. Additionaly it works close range, which makes the vehicle close in putting it in danger of snares and other sources of at fire. IMO it doesn't make sense and doesn't synergise with its intended function. It is there only to somehow "hide" panther's weaknesses and allow pplayers to say it is good.
The biggest issue is that when panther is fielded there are plenty of at sources on the field which screen Jacksons. Pazookas, ptrs, snares, satchels, piats, elite bazookas/piats plus at guns, etc. The inferior range will make panther dive in all these at sources and absorb too much damage. Without crew repairs it will be out of action too long to have impact on the game. If it is unlucky and gets a crit it will be dead.
The panther is not overpriced. Its the jackson being a tad to good for its price. But i dont see that changing as long as heavies are meta, and axis do have more acces to those regardless
It is overpriced imo. If it had more anty inf cabablities and were a premium medium the price would be justified.
Its a vicious circle atm. Allies need such td,s vs inevitable heavy or superheavy unlike axis mostly, but those td,s overpreform vs medium and premium mediums. The panther and p4 feel weak because of it.
The vicious circle can be stopped. Make panther a stronger medium tank and it should be enough to make people build tier 4 for ost. The intended tech should be to build 1-2 vehicles from tier 3 and move on to tier 4. If panther could replace p4 everthing would be balanced. Panther should be similar at dealing with infantry to p4 but retain its at capabilities. Then everything would be back in place imo. Maybe some of panther's health could be nerfed.
