The doctrine doesn't need anymore nerfs until it's mobile defense 2.0
CoH2 will always have cheese, think of CoH like a ham and cheese sub, cheese in part is what makes the sandwich (CoH2) delicious (fun) and will always be there. The hard part is just keeping the balance so the cheese doesn't melt everywhere overpowering the other ingredients of the sandwich and ruining your nice dress shirt.
As unit G says there is also IL2 bombing and overwatch AT arty.
Indeed, but the effectiveness (cost ratio) and execution is not equal with the IL2 bombing strike or OW AT arty.
IL2 AT strafe: 100 muni
IL2 Bombing: 200mu
AT OW: 200mu
Time to hit.
IL2 AT strafe: from border of the map 4s. Because the plane seems to track and shoot from far away.
From the longest possible time on test range map 10s.
IL2 Bombing: at same point around 9s. The plane has to get closer and the bombs take longer to hit. Longest time 15s.
AT OW: for the first shell i seems to take variable times which is around 5s. To receive a similar amount of damage as the IL2 AT strafe, it needs to stay for ±23s on the area without moving. If the heavy tank (i was using Tiger as reference) is neither engine damage or if the ability is casted on dead center around the tank, the Tiger just survives find taking minimal damage at times.
Closest comparison should be the (extinct) single AT Stuka Strafe. Cost 110 muni, takes 2s longer compared to IL2 AT strafe but it can randomly produced different criticals. On 10 attempts i got 3 engine damage and 2 vehicle crew injured. Damage varies heavily depending on hitting angle.
What we could try is giving it lower penetration (around 90) and adding deflection damage of something like 50%. That way it will still be lethal to snared/rammed mediums and Panthers (guaranteed rear armor pens and even with deflection damage when hitting the front armor the rockets should do enough damage to kill a 50-75% hp medium tank) while reducing the effectiveness against heavies by around 33-50% as most have around 150 rear armor. Essentially the same was done for AT Overwatch.
But the commander will already take quite a hit with the increased SVT cost, so it's probably better to wait and see if it'll still be needed to go after the AT strafe too.
This would be fair, it would behave similarly to the AT strafe from CAS commander as well.
