When use Deliverance???

[repoe]

I may be wrong, but I still handle deliverance tanking the same way I handled stance dancing pre.3.0., utilizing cooldown combinations to compensate for dropping defiance (veng,TobConv) the only difference now is I don't lose my stacks and joygasm FC.

Knowing when you can stance dance can't be dictated to some one really, imo.
To many variables, it all boils down to how familiar and knowledgeable you are with the content your running and your job abilities. With experience and time when your comfortable with the content bein ran you'll know when it's safe or optimal to drop defiance. During the learning phases of trial and error in progression I still stay in def full time, unless I'm OT if course
