IMO, a better solution would be to find something new to do with all those AF/OF goods. I'm not sure what that would be, but maybe something brand new.
Maybe some kind of temporary boost for the whole guild. Like spend a certain amount of each AF/OF good for:
* A bonus automatic polish or motivate for every member of the guild.
* X% bonus to Coin/Supply production for 24 hours.
* -X% recovery/recruitment time for units for all guild members.
* X% defense bonus for all guild members when defending.
* X% attack & defense bonus for all guild members when defending (yeah, I know, probably not likely, but I think it would be a good idea, especially in light of the Kraken.)
* X% Happiness bonus for 24 hours
* Automatic Enthusiastic for 24 hours
* +X Tavern Silver for all guild members
* X% Attack/Defense bonus for GE only
* Everyone in the guild gets a small FP package
* Everyone in the guild gets a small Goods package appropriate to their age
* Everyone in the guild gets a small Medal package appropriate to their age
* -X% building construction time for all guild members for 24 hours
* -X% building cost for all guild members for 24 hours
Obviously, these wouldn't necessarily all have the same price. Automatic Enthusiasm would cost more than a boost to Happiness, for example. And these would necessarily be available all the time. Maybe only a few are available for selection each day. Maybe only one is available for purchase each day, and you either buy it or don't. Or maybe a few are available each week, but you can only buy each one once during that week. In any event, you wouldn't be able to get a continuous bonus indefinitely. Maybe the boosts last only 12 hours instead of 24.
It could even be a "lottery" type thing - one random guild member gets something good, like a Large FP Package, a Large Medal Package, a Premium Building, etc.
The possibilities are unlimitless.
