MFing Den of Evil Buged

I heard some rumors from several ppl about Den of Evil being MF buged after lvl 90. I dont know if there is any truth behind it, but it frickin takes forever to get to lvl 90. Anyone know anything about this? Also any fact about how much MF u got on... i hear rumors about 175mf- 450 is buged out, so better 157 or less or 450 or more.
And yeah... any sugestion on where is it best to MF in this 1.10 patch. I am lvl 89 meteor/orb/static sorc.. i eat meph and pindle for breakfast.. however my drops seem kinda poor.
