It doesn't work well on a lot of large maps, and is less broken than CAS (or any other doctrine with Stuka dive bomb). I'd happily give up FHQ for no CAS.
Comparing commanders is not very logical. All I'm saying is, you have to veto certain map only because of this commander, which are some WFA maps built with super concrete. Ost doesn't have a problem, even in those maps 2 pios will finish the game for you. OKW on the other hand, they cant clear those building. Wooden buildings collapse with one volley of Infiltration nades, or even a couple of ordinary nades.
PS: CAS has it's problems, mostly in team games. Stuka AT loiter needs a small nerf, other wise they are fine. Dive bomb is also fine.
