I don't think it is enough to make the commander attractive enough. But maybe only improving the bombs is enough to change my opinion.
Honestly I think the reason why this doc along with many other docs is rarely used is that there are a few ostheer docs that are much better(kinda too good) and completely stand out.
The prime example for teamgames here is Jaeger Armor doc. Spotting scopes that spot half the map for you, recon plane + stuka dive bomb to spot and destroy enemy howitzers and Elefants vs allies TDs. It's one of these docs where you think "why the fck should I ever pick a different doc??" It's ridiculous how versatile the doc is
And this is the general issue with CoH2 docs IMO... especially OST and SOV have these docs that completely over-shadow the entire rest. Maybe those should get adjusted in their versatility
