So yesterday before the weird maintenance, the Arboretum District drop rate for daedroth (sp?) was about 1 drop per 3 kills for any type of loot and for teeth it was about 1 in 12 to 1 in 15. Then, immediately following the maintenance it was about 4 drops per 5 kills for any type of loot and about 2 teeth per 3 kills. That lasted maybe an hour to an hour and 1/2. Now it's like 1 tooth per 25 kills.
On my most recent run, I got 26 husks and 3 teeth on 75 kills.
RNG, blah blah blah, no. Please jack up the rate.
The only substitute for victory is overkill.
