One of the patches, most likely 1.10 had chest rewards increased, i suspect. And now it is too much. It affected raids by filling peoples storages. Before that, a person who’s weaker than me and had 25k food in the tower, was an uncommon find.
Now every now and then i get 50-60k food per raid, my personal record is 77k food so far. And i rarely need to do more than 3-5 skips to find such a rich player to raid.
My team gone up from ~2400 to 2600 in that time, so i would not expect it to affect that much.
Same with iron. There is less iron in there, but still too much. Before that, i had iron deficit while upgrading iron stores, they are expensive and upgrade fairly quickly, so i needed to squeze iron mine upgrade in between them.
now the upgrade takes like 2/3 of the capacity, but still it gets filled before building is finished. So upgrading a mine or even building the 4th mine at all is now a bad investment of time.
It benefits that “double builders” paid feature i guess, for everyone else it means full storages.
