quantams deffinately should NOT have a agent bonus, they are powerful as is and nukes are round ending, unlike OHs which are over after 8 tics.
though most people would quickly disagree with me i woul believe the safer route to banking would be a healthy mixture of pop AND cf banking with of course the 30% TOs. this would mean they need to use BOTH opps to take your income down effectively.
this race is good banker for a SS SD round, but a parxatian, or revalon would most likely be better suited for full family banking as they have a better magic %. as it is possible to pop bank with a quantam, it has a -30% magic defence meaning you have to have TWICE the ammount of wizzies as a partaxian to keep your population safe from ops.
