Benediction "Cast" Time ?

[Kabzy]

It can be rather frustrating, but I do believe it is working as intended. We have buffs in the game, such as Ley Lines, that apply their effect immediately. So there isn't much of a problem server side with 'instant' abilities. But all of these instant abilities like Benediction, Hallowed Ground etc. seem to activate after a quick animation sequence.

So in practise, no it's not 100% instant, the animation is instant and the healing follows it shortly after.

On a slightly different topic, I do think WHMs are often a little too stingy with their Benedictions, sometimes it is worth using it if you don't have Tetra up and the tank is getting quite low. You don't need to wait until they are actually at around 5% or less.
