I used to use the smoke bombs a lot. I'd often drop them on enemy tanks (because I wouldn't realize they didn't do damage; i just saw a Stuka and said... Stuka kills tank. Use Stuka) but I think arty smoke drops. A good way to fool the enemy into retreating a blob or backing up tanks. The problem is that it's only on a few (or even one?) doctrine.
I think we should buy abilities rather than commanders and create our own mix, with some guidelines as to what you can put in a commander. (i.e, not all passive abilities, not all airstrikes, etc.)
