Luchs, FlakHT and FlakHQ changed into accuracy based attacks like centaur with less aoe than before. They're all somewhat better against stuff in buildings.
FlakHT is generally better at suppressing but seemed worse at killing. (penetration nerfed from 20/25/30 to 20/20/20)
Luchs around the same against spread out models and worse against clumped up ones. (penetration buffed from 15/20/25 to 25/25/25)
FlakHQ is just insane against infantry again
While simply an unmentioned side-effect rather than a ninja change per se, most of the weapon changes made in this patch and the last one (flamers, pwerfer, etc) mean massive increases in damage against building garrisons. In this patch every single burst from an infantry flamer is guaranteed to do 32 damage against every single model inside a building (no matter where it hits), so there is no way a squad will survive 3 or more bursts.
.50 cal vet2 got its penetration and damage nerfed to be the same as vet0 gun.
USF AA HT firing cones increased notably.
Sturmtiger aoe damage ninja nerfs removed AND aoe distances buffed up higher than they were back when the unit had 10 radius, so now it will kill 640hp vehicles in a larger radius than ever before.
Avre AOE penetration from 112 to 150, AOE distances from 2.25/4.5/6.75 to 2/4/8 (means the kill radius against infantry actually INCREASED despite the damage nerf), will no longer pierce through objects, +50% damage modifier against buildings so those pesky okw trucks don't stay up. Only thing it got weaker against is tanks with over 440hp left.
Massive increase in DSHK HMG rate of fire at mid and near
Vickers HMG vet1 stacking in a new exciting way, get +25% stacking range every time you enter a building.
Partisan PPSH also got the accuracy buff conscripts got
Brit Reinforce the Front works on allied territory rather than just own.
Ostheer sniper minimum recloak time from 2 to 6 seconds
OKW tank commander upgrade requirements removed so you can buy it with any commander
Conscript received accuracy change was from 23% to 40%
