505mf, in 3 days PBot finds nothing????

OK! WTF?
I use to do Pindle runs manualy and I found sooo much nice stuff... tals armor, eagle, trang belt ETC...
I figured I get PBot it will do the work for me while I sleep..
ever since I started PBot I have only found CRAP...
In last 3 days Pbot found nothing but a frickin KO rune and Gerkes...
Now here is a question.... I havent played D2 for a while, took like 3 monts break from D2...
This guy today called me a newb today saying my sorc has too much MF (505mf reason behind the fact I dont find any good things.. less drops)
Is there such thing as too much MF or what?
