Raven, how much time have you wasted yet on the gypsy camp spawns?? Every time I get started looking for those and picking the locks on the chests, I think of your randomly generated spawn idea that you've posted before.
In theory your idea and something like the gypsy camp "rare items" might sound exciting, but in practice, I think you find that people give up on them very quickly because there just isn't enough spawn or things don't respawn quickly enough and/or the rewards don't justify the amount of time spent. Doing the gypsy camp chests, it seems like 85% of your time is spent running or recalling around hoping to find a camp before it disappears. Unless you're actually training lockpicking skill or really enjoy running pell-mell through the trees, it's not an activity I think the majority of folks will continue for long, unless the very rare reward turns out to be absolutely stupendous new pixel crack and/or checks for 25 million in gold.
