Lol no chance, the Pak howi is a team weapon and all team weapons are safely wiped at range by rocket arty. Building a Pak howi when a stuka is on the field is just throwing away manpower.
Killing a stuka or Katy etc you can only really base dive with a medium tank, which usually means the loss of said vehicle even if you don't find their arty. Why you think this is easier to counter is beyond me.
Sry, wasn't online for some days.
The problem is, that Pack-Howitzer can 1-2 shot a PaK40 etc. without RNG, so it is as effective as StuKa-zu-Fuß doing that.
It would be ok if Howitzer lose auto-fire.
Also leIG18 has to be changed too.
