As it is, when a char is negative SL it takes 2 missions to gain 1 SL.
When a char is positive, it takes 4 missions to gain 1 SL.
I'm proposing to change it so when a char is positive SL, the Mission:SL ratio shoul stay the same. Keep the 2 missions:1SL all across the board please.
Or better yet, set it to 1:1 ratio, so that 1mission gives 1SL, no matter the char's SL status.
