Met 3 DK/Healer/Healer teams last night who were using the Strength PVE trinket - all 3 trained our priest all game with purges and all 3 finished in about a minute (we won one of the games).
Imo it's a sign that something needs to be changed whenever a DPS/Healer/Healer comp is viable - whether it's the trinket or how DKs are atm, it's pretty stupid.
