Your suggestion for Infantry Company is good, but I'm going to leave it be for now. This thread is as much suggesting the concept as the specific changes, so I want to keep edits fairly minimal.
I left Urban Assault Company alone mostly because I hate it and don't believe I'd be objective with it.
I understand where you are coming from but even these changes could only work as an interim solution.
Some things simply need to go/redesigned...USF has undergone so many stock/design changes that some abilities no longer fit the current design.
Imo commander redesign should be made with 2 different approaches:
1) Power level of commander across the same faction:
In other words removed thing that should not exist in the same commander like Priest/Tot/Reckon, Elephant/Recon/Stuka
2) Check individual abilities:
How useful an ability is and how it compares with other similar abilities
With a benchmark of how powerful a commander of faction should be it very difficult to commander's power level right and USF commander are an example of that...
