I know I should have posted this in the suggestion thread but I felt this would be a little more than a simple suggestion. According to the game design document there is no mention of Soldier variations within the same type and rank. I have only played alpha 4 and I did see slight variations within units in the same type and rank. The variations were in form of shield variations at the basic rank and armor, helmets and shield variations at the elite rank, but I saw no stat changes following those variations. In reality soldiers of the same type in the same rank where not exactly the same wealth. My suggestion is to add slight stat change with those variations to represent the slight wealth differences within a rank. Lets take an example: Take two newly recruited soldiers of the same type one would be above average in wealth and the other would be below average in wealth. The richer soldier would have slightly higher quality armor then the poorer solider and therefore be slightly stronger. As they get promoted the wealth gap between them would not change and at the elite rank the richer soldier would still be richer and stronger than the poorer soldier. Same with super units (I know they have only one rank and I am not going to change that).
