One problem with the balancing could also be, that they looked at the top 1% players and their values for offense and forgot, that we have one less GB for the defense. We have the Terracotta Army, Zeus Statue, Cathedral of Aachen and Castel del Monte for the offense, but just the Terracotta Army, Saint Basil's Cathedral and Deal Castle for the defense. If each of these buildings is at level 90, that means the defense is already 70% lower than the offense. Taking this into account, the 3 defensive GBG provide 200% on level 90, a value that's high, but not for everyone easily achievable. Then we need to take into account, that many event buildings in the past either provided only defense for the defending army and not always also offense. IMO, the values in the GEX5 should be halfed, it still be a challenge, but then it would be achievable for everyone, even new players after some preparations. Same for the amount of goods, 10k-18k each week, for a few buildings, that can only assambled after 4 weeks is way too high, if these values would be also halfed, it would still be expensive and would take a hugh chunk of goods out of the game, but it would not ruin every player and their city. And most importantly, it wouldn't force the players to rebuild their whole city.
