I have over 750 something drops and still no mempo. Do you see me posting a rant about it?
With all the drops I have (and have sold) I will have no problem purchasing a mempo from poor shlup that is hard up for some gp.
Face facts, some are lucky and get mad drops, but have the drawback of no mempo. Others have poor luck with drops and get 2-4 mempos out of 50 drops.
IMO it all evens out.
Karma dude, it will get you everytime.
