How to burst aoe ?( newly healer monk)

Interesting, what’s the benefit of hard casting? 1 second gcd on soothing mist and instant cast vivify means it’s still faster or at very minimum the same time to cast, with the added benefit of being able to instant cast additional heals if that target is taking more damage quickly right? I thought soothing mist was such a negligible mama cost it didn’t matter.

I suppose it’s a waste of mana if you don’t need to channel it because the target isn’t taking more damage, but it still seems so small to me. Maybe after I hit max level it’ll be more noticible.
