Necro focus PoHate book broken?

[syztem]

Have not seen one drop on red in months, in fact not since the revamp. Meanwhile many cure shields, earth staves, inny eyes, shattered emeralds, everything. Someone told me they saw them dropping after the revamp, but when the drop rate on earth staff was fixed they had not seen one before that.

spent 8hrs in hate, killed minis, then cleared 2nd floor mobs. Got like 3 hate crystals, 2 druid BPs, 1 druid legs, 2 silverleaf girdles, 1 darkmetal, an ultravision clicky crown. other misc items(mantle, band, various class armor ranger paladin warrior Bps also etc)

Does the necro focus book STILL drop?
