We are talking more about a PuG situation. The planning of letting a tank drop in health to DPS more works more better when both of you are in Discord communicating with each other. When we have a PuG healer instead, we do not know if they are doing what you are talking about or if they are looking at Netflix while spamming Dia and Glare. The healer could very well be a new or rusty player and need to warm up with the basic spells as another possibility. It's not to say Benediction has no place for use though. It can be used in conjunction with Hallowed Ground on wall to wall pulls as you stated.

I can agree with tanks trying out a healer to know what their perspective is like. Please use and stagger your defense cooldowns if you plan to make big pulls. White Mage has more than just Benediction anyways, so they likely don't have to rely on it that much. We have Asylum, Assize, Divine Benison, Tetragramaton as well as the lily heals. My use in Medica 2 HoTs greatly dropped past level 50 since Assize with Plenary Indulgence + Medica often handles the problem good enough. I still have the habit of using Regen, but I have opted not to use it at times because the tank is taking so little damage in relation to my off global heals.
