When the event started all variety of essence were dropping at an out of control rate and now nothing but icescale and energy drops.

Getting a glacial essence is like looting an arcane item. Why does everything have to go from one extreme to the other? I bought some tarlok gem recipes and now I have to do 75 wt4 runs to make one? I just deleted 20 energy and icescale and still don't have enough for one tarlok gem. Very annoying.
