They are both 6.0 right now.
Does gaijin think that:
panzer 4 chasiss = leapard 1 chassis
77mm pen APCR = 93mm pen full calibre AP
60 deg rotation speed = 72 deg rotation speed
3 crew turret = 4 crew turret with shield
4s reload = 0.5s reload
The only thing that zerstorer have is 840 ammo (while leopard40/70 is 228), but because it has 4 guns in total, the actual round is 840/4=210, the persistence is almost the same.
Why put them in same BR? I think they should have at least 0.7 BR difference.
Because the Zerstörter is an Spaa at first and the Leopard is basically a light tank in game.
On of them has both decent antiair and antitank capability. While the Leopard has a more difficult time to shoot down planes, in exchange of having a better time against tanks.
No, it isn’t. I don’t know what else to tell you. 240rpm is not sufficient when every other spaa gets far more. It’s a slow firing (relative) gun with nothing to assist it.
The Chinese WZ305 is rated Br 8.0 because it uses HE-VT ammunition. The Leopard 40/70 with HE-VT ammunition could easily be rated Br 7.7, since firing faster than the WZ would make it more effective as a SPAA.
