A hibernation mode or something that’s non-reversible, comes with a penalty to avoid abuse, and allows for a break here and there would be nice.
Example:
3 day duration
50% decay
50% xp & myst gain
Limit once per 2 weeks
Also could consider x2 structure hp, but if so it shouldn’t be immediate as it’d be the automatic response to being raided.
Numbers can be toyed with, or possibly allow an input for time away and adjustments accordingly, but this suggestion seems like a healthy and wanted one.
