Did HE-VT got nerfed in naval?

With the battle task centering on getting manual aim kills on a coastal boat against planes, I had noticed a thing.

It seems to me recently that HE-VT shells were heavily nerfed. Previously, the only guns whose shells would consistently would explode near the enemy plane and do no damage was the US 3 inch gun, used on Akebono and couple of other ships. But eventually, for every 5 spark you’ll get one shell doing damage.

Now? Even SKR 7 is sparking like crazy, doing no damage whatsoever, not even an “hit”.

Never had an issue with Britains 3" HE-VT (on Tiger), 4" on a lot of secondaries or 6" (On Tiger or Belfast) for killing aircraft

personally doing just fine with 76mm he vt on sparviero
