I belongs to a small alliance and the war become impossible. We have beginers with teams about 3k of power. And we awais face stronger teams and we get less points to beat a stronger team than the enemy. So the enemy, with stronger teams awais beat our teams at once and we have to attack more and get less points. Is just impossible to win.
This happens sometimes, especially if your alliance won several of your previous wars. The game will continue to give you tougher and tougher opponents until you are “forced” to lose.
When you lose, your war score decreases. You will face less stronger opponent in next war. Until you alliance finds its place in the war ladder. That’s all.
