It seems like every players Bravery and Aggression attributes are really hard to level up; so I was wondering if the devs would allow players Bravery and Aggression attributes to grow with the use of morale boosters of course if the player's morale is at 'Very Good' and below then their Bravery and Aggression attributes can grow if morale is at 'Super' then no..

To strengthen my case every season we level up and I check my players Bravery and Aggression attributes they are very low for all of the players and those attributes hardly increase through regular training and overall Morale correlates to Bravery and Aggression as they are psychological attributes.
