Double Deathbringer's Will for Enha shamans

Having played mostly on Molten WoW and a little bit on Blackrock pvp server, I have noticed that people role the same trinket twice. Warriors, Paladins and DK's would go with Deaths Verdict HC in the first trinket slot and Deaths Verdict NORMAL in the second trinket slot. And the same with Whispered Fanged Skull, one HC and one NORMAL.

DBW = Deathbringers Will.

So now the real question: Why haven't i seen any players, or donors, with double DBW? AND/OR "Is double DBW possible (One HC, one Normal)?

Is it not possible, because your trinket procc is active for 30 second, which is too much or something ^^?

I brought this topic up cuz DBW is ofc the most powerful trinket for melee and huntards.

Ty, hope you can understand wrote this in 5 mins

And OFC the tittle could also be called Double DBW for Melees. But i prefer Enha shamans nonetheless.

As far as I know only normal+HC trinkets from ToC can be equipped at the same time while its not possible with trinkets that drop in ICC.
Also, DBW is not as good as u think. The best trinket for a EnH is STS HC followed by Herkuml War Token.
DBW hc might outperform Herkuml War Token in PvP when u need the extra ArP.
