Ok, so i officially have the worst luck in trinkets ever...
I've got 60 frosts and nothing to spend them on other than primordials so i thought about buying a trinket. I want to replace my NIC that i use only for the static spell with....
Purified Lunar Dust - nice big chunk of spell power
War Totem - just for the static haste
Quill - to macro it to meta ignoring the hit...
That's of course until i'll finally see any other usefull trinket. I have never, ever seen a good one drop!
