Depending on your class there are ways to improve that result. A Bourgeois for example, with max Stockpile would certainly help with the quantity when picked up. Using the Medal of Fortune from the Item Mall will essentially double your chances, per hour, per use. Partying with a large/larger group of people will help increase the kill/drop rate per hour. Of course, trying a different monster, such as the Orpe Lukete or Krawfy Swordsman may help.
Then again, other issues could arise, 1) 1 hour may not be sufficient amount of time to gauge the true availability as luck does play a part. 2) The more people that eventually fight those monsters, will increase its availability. 3) The drop rate is deemed too low and needs to be increased. 4) The drop rate is deemed acceptable, yet the availability of monsters who drop it may need to be increased.
Hope this helps!
TBH i think stockpile needs to get looked at...Ive tested my borgs vs my other chars on the same mobs...(back when drops werent garbage in orlo) my scouts average lisent drop would be about (4), but ranging from about (6) or (7) to (1)...my borgs? a flat, steady, consistent...(2)....mabe a (3) with a powder....
