I am just curious if my fellow healers use LB when they notice the DPS members of the group save it/don't use it [when available]?

As I continue to try and optimize my role, this is something I noticed after getting into the habit of letting my tank get pretty low before hitting them with Benediction/Lustrate when these abilities are available. I do this more as SCH than I do WHM since Bene is one-time cast with a really long CD, but lately if I notice the DPS aren't using the LB and saving it, I will DPS like crazy and burn it up for a free big heal and then continue to DPS until I actually have to burn MP on healing.

I am posting this because I usually get frowned upon for doing this, but it just drives me crazy when I see the LB meter glowing in my face pull after pull, after pull, after pull. It is usually a tank who actually thanks me for doing this^^
