For me that might mean complaining. I like to compain. Especially on the internet.
Everyone does, it provides for passion and confidence in opinion. Structured, realistic, affecting (on troops) weather patterns would give the game a more 'alive' (life-like) feel that would cause the game to breath and behave very involuntarially. Couple this with a 'thinking' AI on the battle field (if possible) and this provides the player with alot of pleasure as he has to out maneuver both the weather and the AI. Gone would be the days of a visually stunning game where it's crappy mechanics are made more obvious due to the polar differences between the visuals and the game play.
