How long will it take a low-level Druid (without a ring) to level from 17-22 ... ten hours? The
wiki reports list nine players who got their ring in under ten hours, and the majority got it in five hours or less. The less lucky ones needed 6, 8.5, 10.5, 18, or 50+ (!) hours, and there are also reports (all ten hours or less) where no ring was acquired.
The right thing to do would be to put all those reports into a table and do some math ... although that would still be flawed, because some reports are for single spawn points, and some (most?) are for the double spawn. Instead, since there seems to be roughly the same number of ring/no ring cases, let's just double the time of the ring cases. Now it's 10 hours or less for the majority, but the unlucky ones will need 12, 13.6, 21, 36, or 100+ hours.
In other words, most will get the ring while they're still getting XP, and if they stick around a few hours longer, even the 12/13.6 guy will get a ring before they leave. But, if you are that unlucky person who needs 100+ hours, you
will level out of LOIO long before acquiring a ring. Like everything in EQ, it's a chance.
Still ... even in that worst case scenario, all you lost by going to LOIO was a minuscule amount of plat (I can't believe the plat drop difference between LOIO and Warrens is that significant), and a similarly small amount of faction (remember, a high level character can clear the Warrens in about half an hour, so at most it will take them maybe an hour to match the guy who leveled from there 17-22).
