You should be doing quest bugged boss runs, and switching mf when killing the boss, unless you fare almost equally fast with the mf gear on. And/or skip monsters.
I have about the same when switching gear to kill hell diablo, quest bugged. Took me about 50-100 runs to start getting good gear. But the best item i have, oddly enough, came from a normal monsters in chaos sanctuary, lol.. 99% perf griffon's.
