There are a number of leaders in the game with shock or fire values of 1 (or even 0). Since generic leaders have 2, it is my opinion that any other leader should have at least 2 as well.
This guy is an example of a leader that could do very little but be in the way. With his rank he would enter battles and steal command, thus making chances to win less, independent of the former leader (since he is worse than 2-2-2):
Fire 4 is great, but shock 0 would mean he would rarely be used anyway. And movement 1? I just don't get it. Why have a leader in the game that is worse than the common colonel?
My suggestion is of course to make any 1 or 0 into a 2 (for fire, shock and movement). Alternatively, but less interesting, deletion.
