Congrats, that was a fairly effective first take-over of a 12. A couple of things you might want to tweak.

Workers layer in most situations against pike-cav-ram. Adding both worker and ram sometimes acts as a double layer. At a minimum in all waves prior to clearing archers, adding workers means one round that the defending archers aren't shooting at your own archers, so the potential benefit to your damage per battle is significant.

Normally warrior+sword as a combo would not effectively layer against the advancing warriors, but note that your first fight after clearing the arch went 11 rounds. I keep getting reports like this too, which suggest that the point at which the AT cannot effectively clear the sword (or even pike) layer in a single round is fairly low. I'm going to keep playing with the size of these layers myself and see if I can decide an optimal size. Obviously one more round of 50% (or even 100%) damage from the archers is much more valuable than the combined damage of 1-2k additional arch over several rounds, which may be all it takes.
