Snip....
Well that's a nice sentiment, in the history of game development I have no doubt that being able to create a realistic and balance game is the ultimate test of a true immersive experience.
However, we live in the real world and as such the representation of the events by this game and many others are of the real wars, which by their nature are inherently unbalanced. If two opposing forces where always balance, no one would ever win a war or wage a war again, thus war is the mistress of innovation to gain a advantage to the other force.
Back to the game, even your example is poor at best, which both revel that you do not have a understanding of the game and secondly attempt to reconcile two contrary forces is abysmal at best.
For example, you belive that units clip size could be increase due to the real life version of the weapon would have "little to no effect" in performance which is utterly absurd, units Total DPS can be cut back if excessive time pases between reloads. Which is why there reload bulletins, concidently the bulletins that a player should desire the most, are labeled "rare" And are often reload speed for different units to compensate for. quick ejection on expended mags.
As this is not a historical thread, which this thread belongs in either "wish list" or "other" section in the forum considering it has very little value as a thread in the main lobby. I will say that you fail to understand even the basic nature of armed conflict, in which I personally hope you take your time and explore the subject out side the comfort of your PC and perhaps dive in to the occasional book.
I like to point the Irony of the title of this thread, "myth1: Realism Vs balance" as reality of conflict of humans is by its definition a unbalanced action, much like the conflict this game is portraying.
Lastly, any changes no matter how minor effect the game as a whole, changes should only be made with best available data on the GAME and NOT on the subject matter that is based off. In order to created balance in the GAME, it should use game data and not make changes based on "Historical" reasons. It definitely shouldn't change based on the feelings of others And especially opinions based with little knowledge to the game itself.
