Ok I need to add an edit to my above response … there was a bug report previously about a month ago where Ignasis states the settings that had to be changed:
But still … private server owners would have to know to look for a bug report asking where the thrall decay settings are before they’d find out about them and that they might not be in their ini file … so still very poor implementation of the change. Not in the patch notes on all three platforms in PLAIN text what they are… and not even IN the ini files that server owners see … so 26 days after acknowledging the GUI might not have those settings … seems Funcom still hasn’t fixed it …
(When Funcom implemented the feeding system the patch notes clearly listed the settings that server owners or single/co-op players would need to change with relation to it.)
