- The Jackson has the best penetration, the maneuverability to chase down retreating vehicles, the biggest penetration boost with veterancy and an ability that boosts its penetration.
- The SU-85 also has an excellent gun and the powerful Focused Sight ability at Vet 0. It's also the cheapest, but it's the least maneuverable.
- The Firefly has no penetration buffs with veterancy and a terrible rate of fire that doesn't really up for its higher damage gun. It's hamstrung largely for the sake of the Tulip rockets, which already have a hefty munitions cost to limit them.
None of these TDs are unusable, and you build all of them if you need them. However, given they serve the same role and face the same enemy units, shouldn't they be balanced against each other?
They're currently not. The Jackson is better than the SU-85 is better than the Firefly.
The question then is which to balance them around? Which tank destroyer is at about the right power level right now?
