Related Tip:
If your alliance is using 4* heroes for war defense team, but only have enough 4* attacking heroes for the first half of war, post a “Hit list” for the second half of war when your alliance is using 3* attacking heroes.
A “Hit list” is a list of good enemy targets ( high point value, low defense value ). Your allies mob the first defense team on the list, whittling away at it until the enemy defense team is killed, then move on to the next enemy team on the “Hit list”. Keep going until out of war energy. It might take 3, 6, or 9+ war energy, but depending on the team kill bonus, it can double or triple your second half score for your whole alliance.
Good “Hit list” targets
Don’t have healers in the corner,
Don’t have riposte ( unless the riposte is the team’s strong color, but that is another post about how to defeat riposte without a dispeller ),
Are alive or reviving shortly,
Have multiple defense heroes of the same color,
Have multiple slow mana heroes,
Have three, or more, defending heroes with special skill damage all enemies.
Response:
@Gruff, Konijntje is correct:
To rephrase:
Since you team is only worth 20 points, you enemy can ignore your team, which frees up 6 enemy war energy for them to decimate the stronger ally teams. Unlike raiding, an alliance can use 3, 6, 9, or more attacks to whittle down a team, especially if all the points are concentrated there.
