If you look at the ground tech trees, you can find several examples of similiar ‘copy-paste’ vehicles, both in the same tech tree or in different nations. For example, the ZTZ-88A/B in Chinese tech tree, the two T-72Bs in USSR tech tree, 4 similiar T-72M1/T-72A tanks in 4 nations and the Leopard 2A4 tanks.
It is boring to research the vehicles and their modifications that have barely any difference between their in-game performance. Especially those Cold War-era and modern tanks, which cost hundreds of thousands of research xps each, and make you grind for them repeatedly. They are just meaningless obstacles on players’ road to top tier.
So why shouldn’t we change this situation?
I would like to provide some examples to illustrate my idea.
For the ZTZ-88A/B twins, we can give ZTZ-88A the DTW-2-105 round and lift it to 9.3 br, while the ZTZ-88B remains at 9.0.
The T-72B(1989) will receive 3BM60 and a 1000hp engine and be moved to 10.7, and change its name to T-72BA.
Some of the Leopard 2A4 tanks can receive DM33 or more advanced rounds, or even high-res TVD sights if they have such modifications in reality, and adjust their brs.
And for Leopard 2A5/A6, we can lower the Leo 2A5 to 11.7 and nerf its APFSDS to DM43. The German Leo 2A6 can upgrade to high-res TVD and change its name to Leo 2A6A3/A6MA3.
