with my own stat weights, using pure napkin math i got the following values
will of unbinding - 3106.8
insignia of corrupted mind - 2354.8
darkmoon:volcano - 2108.2
these are the top 3.
this is for destro, ilvl 385 - and all these trinkets are the 397 versions
just possibly as a reference point to relative power, they are also the top 3 for affliction, as the stat weights are very very close
