Changelog
The points and cash per minute granted by bases has been reduced by 10 times. Each captured base now grants 3 points and $600 per minute(previously 30 points and $3000).
The timer will run every 20 seconds, so technically your team will gain 1 point and $200 every 20 seconds for each captured base.
If your team is hit by the Casualties disadvantage, the points per minute changes to 1 and cash changes to $200. Technically, when affected by casualties every 20th and 40th second will grant you nothing, hence leading to the above mentioned numbers.
