Not really they still have access to grenades and vehicles from LT (which is currently a far better choice than captain). They also have a number of doctrinal options.
If something Ostheer have trouble vs USF and there is little reason to buff Ostheer.
Moving to captain ( not require second tech) is neither that late or expensive to get access to.
My point is that USF went from having limited access to indirect fire to have more than they need so some of these units with either be OP or UP due to overlap.
There is simply not reason for mortar/howitzer/Scott/Major barrage all to be available stock and with little side tech.
No rocket arty, no heavy tanks, has to tech for MGs. I think it's ok if USF gets decent arty options.
Complaining about pak howie just marks you as a noob. Theyre easy to decrew, theyre easy to flank, theyre easy to counterbarrage(looking at you axis). Theyre stupid, stupid easy to counter. It does its job effectively, its a shock unit. Learn to adapt and overcome Axis players.
