(Certainly take a bite out of folks using 100-1000's of alts- mapping and advanced java coding to gain an advantage of those who aren't programmers.)
On the flip side I'd like to see decay rates tripled for abandoned steads... I like finding useable materials and such that have been discarded; but there resources don't encourage me to create my own... and can be a major distraction.
Finally- Mine shafts degrade and disappear... yet we have the ability to find them again. What a hoot it would be if we could 'rediscover' materials from previous owners...and/or random loot building new mine shafts over mines that disappeared from decay from previous owners... etc.. A lot like finding stuff in stumps... but 1000x better
