Well, the truth is that I failed and I didn't even manage to DoC my last Rip there so what you are seeing in that log has nothing to do with DoC. Maybe my comment was a bit off topic and not really related to which one is the "best" talent for raiding. I just needed to vent a bit about how ridiculous the RNG has become with the combination of extremely strong RPPM trinkets and being able to keep a snapshotted bleed for 25% of the fight.
What talent that is best is quite obvious. Are you failing due to enrage, then maybe try DoC. Else I would always use HoTW. Tranq + blanket rejuvnations are extremely strong. For example on Jugger 10 man hc you can pull 130k + hps for 45 seconds (this is with 30% overhealing):

If anything, that should be considered OP.
