It would be interesting to add that to the meta-challenge system.
- Challenger declares attack on hex
- Defender is chosen and declares how many points will be used in defense (max 2000)
- Attacker declares how many points will attack (not more than 500 points above defender total)
I attack Ranov Space Station. Defender commits 1850 points. I attack with 2000. We fight a 2000 vs 1850-- the defender preserves more units but has a higher chance of losing committed forces.
