All players requests proper solution for oil, i have one solution what is if PvP defence win reward small amount of crates, some players again starting playing this game after this update come. We are raising hand in this linkGame Improvement Suggestion - Reward for Successful Base Defense
Do not add defence reward oil in war map players mis use this to attack and lost with allies, only for PvP. Reward example:- defence win against low lvl or high lvl reward like 10% oil of total troops lost by enemies. For example. Enemies total repair cost 1500 so defence reward 150 oil crate, if enemy repair oil cost 15k then reward oil 1500. So its the solution for all . Low lvl defence win low oil reward high lvl defence win high oil reward. Thank you..
