So I've noticed some people are using the new beacon of light glyph after the patch. This healing idea came to me when I saw the new beacon, with no duration, mana cost, and only a 3 sec cd. I'll probably try it out when my addons are fixed or in MoP when health probably won't shoot back up as fast.
Glyph of Beacon of Light: Removes the global cooldown on Beacon of Light.
Remember using WoG/Holy Light/Holy Shock on your beacon target is a waste of the heal transfer effect and does not grant a holy power from Tower of Radiance. In addition, using your 3 AoE heals on the raid while the beacon target is at full health will also be wasteful overheal (no mastery shield for beacon heals).
My method is for example: if you plan to heal your beacon target with a WoG then a holy shock, first switch your beacon to another low health raid member, heal your target, and 50% of your healing will be transferred to your beacon target rather than just being wasted. Then switch your beacon back to its normal target. If your about to AoE heal spam, and your beacon target is at full health, switch it to the lowest raid member again.
Now I realize this would take some extremely fast switching to reap the entire benefit of the BoL glyph and is very complex. But hopefully there is an addon that could assist with this if we aren't able to look into this ourselves.
