wait are you new to the game? from your forum account it seems you have join from 2017 but only knew the morale drop for every players even after you trash other team 21-0 "lately".
it has been like this since forever. only the fire can save player morales (keep em at high morale for few matches)
others will drop because nodeus wants everyone to use boosters and if you dont have any, well you can always buy em
(more profits to nodeus, dont need genius scientist to figure that out)
