I can't call that a team, in my opinion, you should remind them to donate at least and use war troop during war. BARCH IS ONLY FOR FARMING. kick all those who don't follow your rules.
If this keeps up on your clan, you will still be the one who loses in the end even if your clan won the war, you will still gain little because of your expenses in resources.
Yes.
yes, loot should be better for three stars, but loot in general war loot should be higher, and it should be easier to three star.
While it is possible to profit from war, people who try this (without success) are derided. The biggest profits can be made by one starring. Doing that will see you kicked.
To to make it easier to three star (a little easier, or "possible" for more people), increase the time allowed to complete the battle. 3:30 for TH10; 3:20 for TH9, 3:10 for TH8
