I believe, SG got plan for inclusion of raid formations.
What I mean with war formations is basically, that the leader of alliance and chosen 3 commanders can put ally hero setups on any of the available locations (front, back, sides etc,…). Elders in alliance have option to propose their location.
REASON for it, enemy must first break the front line, before they can fight other hero setups.
FRONT LINE BONUS (edit) : 10% to defense for all defending setups on front line
And once you break the first line, you can only go for one hero setup left or right or forward.
LEADER can promote 3 of his teammates to siege commanders. After the first line is broken, they can go for any hero setup on the field (as well as leader).
This would ADD extra immersion and planning during pre war time, as well as alot of extra dialogue and tactis during war time.
FOR EXAMPLE : you can put your strongest teammates in front, so they hold the front line for longest, or put them furthest behind, so enemy has to risk lesser hero setups for breaking front lines to still have power for last line.
Killing LEADER amounts to extra 100 points. KILLING COMMANDERS amounts to extra 50 points!
Thoughts? I think this would make wars alot more exciting and engaging
