The mail problem is - i get more medals while def than trying to attack.
Before patch i get 4 medals and i was trying to win no maater what , coz i get my reward, now if i simply def i could get 6 medals and if i went to attack - only 3.
So the point is - give to 8 medals 80 comms, and for winning team 20 more. Simply this will fix warzones.
