And the US has nothing like the werfer stock, so they get things like the pak howy instead. They don't have abrumbarr so they get the Scott.
Unless of course you think the calliope should be stock instead? We can have that conversation, your call
with the same logic:
"The Ostheer have nothing like the Major barrage stock so they have Wefer."
This is simply the "grass is greener on the side of fence mentality". The pack howitzer has little common tech wise, cost wise, timing wise or damage deliver wise with the wefer.
There is little comparison between the Brumbar and Scott also.
In addition Ostheer as faction have little to do with USF when it comes to design faction. Comparison between the Wefer and and Pack howitzer are simply misleading.
If the pack howizter role is that of wefer, it should be move to T3and the Scott should become doctrinal,so pls lets drop this silly argument.
Bottom line is that USF currently can turtle up nearly as good as Ostheer using stock units and the Pack howitzer gives them the edge. Unit is simply too powerful for its time frame.
