It’s very important to split war loot as two. One is war participation along with war score and defense and second is War win or loose.
Now, if one alliance lost in war, they are getting very very worst loot, even some players did good job in the war, which is discouraging the players.
This is why, the lowest scorer on the winning team will get better loot than the top scorer in the losing team. Alliance wars is a team effort, you win or lose together.
If your alliance is losing substantial more than they winning, I for one, would be terribly discouraged. If this is the situation for you, your alliance should revise your war strategy.
