Right now, the trait selection method involves having to choose between a space or ground trait at each promotion. I know I tend to go for space over ground since I spend my time in space engagements. However, this can make a character weak when a player decides to do ground end-game activities.
A better method would be to split the selection into choosing one space and one ground at each promotion from Lieutenant to Captain, and then a single choice at each of the Admiral ranks (the player would know by then how much emphasis they want to give to one side of the game over the other.
This give a player a more well rounded Captain for the end game activities.
Under my idea you would get more choices; right now you get only one choice at each level to either get a space or ground. I propose adding an additional choice at LT to CPT level, but the one is for space and the other is for ground. Isn't more better?
