Capital Gold per attack is a useful descriptive metric, but it is affected by district state, cleanup attacks and target difficulty. Use it alongside attack usage, participation and several weekends of history.
Reward useful cleanup
A player finishing a difficult district may earn less Gold while enabling the next attack. Do not rank members solely by total loot.
Track the right trend
Over time, watch participation rate, unused attacks, total Capital Gold and attacks needed per district. These measures reveal more than a single leaderboard.
