The 222 has the same gun as the Luchs, so there’s no way they’ll make it a LV counter.
The 222 uses a completely different gun than Luch in game, with completely different properties and mechanisms.
And increase the power level of the 222 should focus more on the durability of the vehicle and not its DPS. It should serve as a very soft counter not a hard counter.
The idea is to make ostheer less vulnerable to LVs not to make them dominate LV play.
