Mirror of Brokem Images for hard modes?

[godisafk]

As a post poped up in the US forums about the usefulness of this trinket for hardmodes, my guild officers are now all going crazy telling everybody in our 10 man to get the trinket for our hard modes. We are currently 3/12 10man HM and doin just fine progressing. My question is the utility of this trinket for an Unholy Deathknight and is it worth dropping one of our DPS trinkets for this one. Maybe in patch 4.0.6 when mastery becomes better it wont be that bad but with AMS, AMZ, and IBF I dont see a hardmode mechanic (in videos) where in 1min i will use more than 3 cooldowns or else i wont survive.. maybe Phase 3 of Council

It has its uses yes, probably best utilized in neffy hardmode.
