I am pleased this conversation is happening. There is an old adage about people who know the cost of everything and the value of nothing, and there are many players like this. They can tell you the angle of a Panther G's armour on a Tuesday outside Briansk in 1944, but will happily drive infantry in trucks straight at a front line (insert your own favourite gamey tactic here). It isn't that you can't do it, it isn't even that it may sometimes get the result you want (despite BFs best efforts to stop players exerting too much control). The simple fact is some people are enjoying playing it 'properly' and learning even more and getting more reward from that playing style.
In my boardgame days there was a simulation called Korsun Pocket by Jack Radey. In his rules - at the back he had a paragraph for the gamers (rules lawyers we used to call them in boardgames, people who misinterpreted the intention of a rule to gain an advantage), and his paragraph read (I am paraphrasing) - when your opponent next leaves the room, take some of his counters off the map, I said its ok to do this, so you can - his point was if you need to win so badly - cheat - its ok - its just a shame you don't get what winning properly brings.
And even as I say that again I can counteract it by adding every one has paid his dime, we can play how we like. But it is frustrating to play people who don't play like you, and the game can never keep folk in line on its own. Players have the ultimate responsibility. And I guess at the end its up to us all to enjoy it, maybe like any good relationship tho, we should try and ensure our opponent is enjoying it too (as we tear his armies limb from limb).
