Edit Title: It´worth cast Bane of Agony on trash and on multi-dot fights?
For Demonology Warlocks:
I saw some demo warlock POV and I don't see any of them cast BOA on a multi-dot fight such as Warlord hc, Warmaster, Madness.
Tbh I think I miss understood the utility of BOA... Which best time to use BOA if exists one?
I'm asking that because when I dot a target that isn't the main target I use Corruption,Immolate,BOA. I'm doing it right?
Some feedback would be appreciate.
