Facts observed in game :
Fresh new Soldiers with low strength are not usable - low amount of basic equipment limits their offensive and defensive capability to the harmless level
Skilled soldiers with high strength can carry more than could fit into inventory.
Problems specs :
1. Strenght influence on weight capacity is too steep.
2. Strenght 100 basicaly removes weight management, which is wrong.
Current Status
Rule: soldier receives 30 carrying capacity plus 1 point per each point of strength
str 100 carry 130
str 70 carry 110
str 45 carry 75
Min 75 Max 130 Range 55
Proposal
Rule: soldier receives 80 carrying capacity plus 0,5 point per each point of strength over 40.
str 100 carry 110
str 70 carry 95
str 45 carry 82
Min 82 Max 110 Range 28
As you can see, in the proposal change low strength has higher carry capacity while top carry capacity is lowered.
Also min/max range is significantly lower. No more superheroes.
On top of this :
Weight of more advanced armour need rise gradually: Each Higher level armour is 2 points heavier than previous. This way rising weight capacity is spread between offence / defence. Also it brings variety, when new soldiers could sometime use old armour because of weight. Small bonus : not all soldiers will look the same.
