Thanks for the feedback!
Balancing is the issue here, I did not want to have the numbers carry over as this is a friendly themed scenario and if someone goes against a beginner player in the first round they may have a huge advantage in the second.
With regards to the seed gathering, I thought I put in that you can only pick them up off enemy models to prevent exactly the scenario you described.
Having seed sacks scattered may be a better idea though, and you are right, table halves/quarters would likely be better than deployment zones.
I kept both sides having fields in the first two so that people had a decision to make on how they split attackers and defenders, but open to suggestions on making it a single field in each, or changing it totally!
Just love to play these kind of things and figured I would see if others still show interest!
Attached is an update with the suggestions regarding field placement.
