Great, except this is a video game.
You are obviously over-simplifying my statement and drawing uninformed conclusions. Of course this is a video game, and I don't believe that fact was ever up for debate.
There is an inherent paradox in a realistic game. Obviously, if this was an instance of complete realism it wouldn't be a game. Conversely, if this game possessed no realistic attributes, how could it possibly claim to be realistic (which it does, to some extent)?
Realism is not a dichotomy, but a spectrum. This game is neither completely realistic or unrealistic, but a point along this spectrum. The point at which this game should be placed upon the spectrum and the rightness of that location is subjective. The majority of RO veterans and those who seek realism would desire a location further along the side of realism, while those seeking playability at the expense or realism, like yourself, would tend to favor the other direction. Realism and playability are not mutually exclusive, but there must be some sort of compromise.
I would personally favor maps that are more realistic and give one side the obvious advantage. It motivates me to overcome that handicap, and it more closely resembles realism.
