So... under the new system, what does the Banker even do anymore? I know that "power doesn't just come from buttons". Generals don't get many buttons either, but a good/bad General can make or break a realm. It seems to me that Bankers are becoming not only non-essential, but unnecessary. I'm starting to think that the new food trading system is too easy-to-use and transparent. There is no need for a central trading coordinator anymore. And if the wealth tax is gone as well, what's left? Can Bankers still call early tax and embezzle gold?
How about letting the Banker set the four government council member's share of the Ruler's tax income, but give the Ruler a veto power? The Ruler can have three check-boxes that say whether they want to give the other council member that share, or keep that share for himself. In other words, let the Banker cut the pie and hand out the slices, but give the Ruler the power to eat any and all slices. After all, it's his pie, err, gold.
