Ive been finding some good stuff from TZ areas
According to Silospen, now some TZ mobs have better odds at Tyraels than the Bosses.
I havent looked all the items and all, Tyrael has more or less been my point of reference lately.
Also note that with the new items, the loot tables of every Boss have been widdened and the odds of the previous uniques have been lowered just by that fact.
This thing by itself should not make you feel like drops are shit tho,
But odds regarding let's say Tyrael on TZ Baal have gone from 1:16k or so (with my MF - 586%) to 1:17k something.
And the lowest I have found with the same MF is something at about 1:10k, on Defilers IIRC.
I have yet to unravel everything behind this but it looks like farming TZ uniques is now better than farming bosses on a pure odds point of view., whereas before, sniping bosses (especially Andy) was absolutely obnoxious if you were to target farm TC87 and such
