I think the resources at the current ratio on test is good for large tribes. Doesn't seem that hard to get, and most large tribes already have these things stock piled.
For small or starting tribes I think its pretty low. 0 granite to start building, then after a few buildings its like 5 granite every 22 real days.
Currency Bonus:
I love the new currency upkeep bonus outside tribe area. I think its a minor bonus but people likely will still want the bonus.
The cost seems ok maybe a bit LOW for but it is a small effect (for my tribe its 9k Currency every 22 days for a +4 bonus to all stats outside tribe area, for all members)
I also think this upkeep is based on the current activity level of the game and tribes. Overtime when players are more active, and the game is more active, I believe this upkeep should be increased.
This is coming from a tribe with 90+ PAID accounts in it, yet only 10 active accounts. We can easily keep up with these upkeep costs for 6 months real time only part of a play day of gathering.
I expect if we had 50+ active accounts/members it would take less than 1min of each person a REAL MONTH to upkeep that, which means it would be way trivial to have an effect.
So in summary, I think the rates are good for putting in now, but if you looking for long term when the game is more active, they would be extremely low.
