There can be no cogent expressions on balance or design from a casual, for they have not grasped the answers that will change their meta right in front of them.
But, and here's the method of transformation, if they're not expanding their knowledge of the game they either A: don't care, or B: are blocked by a lack of intuitive design and lack of effective communication between the game and the player.
It is the developer who fails in the latter regard. This is the origin of good design mentality.
Or C, its because they are fucking stupid and their opinions don't matter! =D
There's a reason people here stay away from cancer like the official forums. Primary example can be seen if you flip through any number of official forum balance posts. The most hilarious example would be the user called Genobi.
Edit:
Yet again I disagree. Obviously "better pathing" is something we all want, but auto-vaulting does not address any of the real issues caused by ghosting. Furthermore, it does interfere with the behavior of existing and intended mechanics such as actually complete barbed wire. Vaulting should remain a conscious decision.
Although I disagree with you on a lot of your other points, this actually made me feel something wrong inside.
Really, why not have it? Seriously, if I want my troops to go somewhere, I expect them to do the utmost of their ability to complete my movement order. If I wanted them to retreat, I expect them to be smart and not to run a mile around a fence in order to SURVIVE. It's the same as arguing for less freedom of movement. In the end, what harm could this cause if this was to make it into the game? If you want to limit some freedom of movement, let it be up to the mapmaker's craft. There's literally no harm to this other than freeing up APM to be used elsewhere.
