I'm not sure the best place for this post, don't believe it's a bug, but it's essentially feedback for the developers. What needs to be fixed are the towers that the defenders can build in settlement battles. Tier 1 and 2 seem to be okay, but tier 3 and 4 seem to attack ally troops more than the enemy. If you look at the images below, despite there being clear blobs of the enemy, the hits are always on the edge between where the two units are fighting, and almost seeming to hit more ally troops than enemy troops. And I've noticed this in battle after battle. I usually still win, but I've also lost battles because I'm taking too much damage from my own towers!  It's very frustrating.
