Dark Knights, Blackest Night and Holy

[Tint]

There is one other perspective that requires mentioning: Indiscriminate Holy spam can make enemies stun immune, which means your tank no longer has the ability to stun a baddie who's winding up a large AoE or a party-wide attack. :3

Then you push the mob with Fluid Aura to cancel the ability yourself. Okay, there are some occasions when that doesn't work, but normally it's not a problem.
