I've currently cleared all the dungeons in my reach and the only place left for current "exploration" is the Boss Rush for Jade Way... well, the first three bosses anyway.
However, the first two of three bosses don't seem to drop any loot, and this is otherwise rather poor as experience farming goes.
Is the only point of boss rush setting a time for the bragging rights, or does mad loot reside at the end making it a worthwile way to spend a day?
