Not enough Iron Age (for one example) goods at treasury? The few or the only one Iron Age player (others have already moved to EMA and beyond), only has a low level Observatory or Statue of Honor that cant provide enough Treasury goods for the guild actual needs?
I solved that in my guild by trading down a few (10, 25, ?) SAM or other high era goods, one era at the time, until reaching huge amounts of Iron Age goods (besides, my individual stock at Iron age usually stays over 2000 each), then boom donate 500 or 1000 or 2000 Iron age goods to meet the goods needs at Treasury. Problem solved, call me when more is needed. My Goods x FPs deals keep my Iron Age stock healthy.
And work with the Iron Age guy to improve :
- raise the attack GBs at city to make easier for him/her to fight more at GBG, to consequently win more SOH fragments, level up his SOH / add Roads to Victory, to improve Treasury donations,
- Make a FP x goods deal to get him an Arc and an Alcatraz if needed.
If he/she is not interested to improve then remove him/her from the guild. Not discrimination, same would be done with players at other ages. If not contributing enough, and not interested to improve, then out.
Edit: We had a similar situation at a guild when a guild member become the only SAAB player in the guild, who had a low level Arc not providing enough for GBG guilds needs at the time. That was probably since his city design was more inclined to WW Farm and his GBs were not as developed as other high era players. We had to convince him had to start a campaign to add more levels to the Arc to solve the issue. If not agreeing to raise his Arc, or use contribute SAAB goods to the Treasury in other ways, we would have to remove him from the guild.
No discrimination due to age, but the problem may arise more at lower ages.
