Been thinking that it would be nice to have a major glyph that modifies Word of Glory (or Eternal Flame) to make it somewhat similar to the Cataclysm talent "Guarded by the Light":

Glyph of Glorious Protection: When you cast Word of Glory (or Eternal Flame) on a freindly target, it gains an absorption shield equal 100% of any over-healing, lasting for 6 seconds. Also reduces the healing done by Word of Glory (or Eternal Flame) by 20%.

I'd say make it available to all specs as well. To illustrate how this glyph would work out in practice here's a few examples to compare the glyphed and unglyphed versions of Word of Glory assuming a base heal of 10k:

First Scenario
Player A casts Word of Glory on Player B
Player A's WoG heals for 5k (5k over-healing)
5k effective healing.

Second Scenario
Player A casts Word of Glory on Player B
Player A's WoG heals for 1k (9k over-healing)
1k effective healing.

Third Scenario
Player A casts Word of Glory on Player B
Player A's WoG heals for 4k (4k over-healing)
Player B gains Player A's Glorious Shield (4k remaining).
8k effective healing.

Fourth Scenario
Player A casts Word of Glory on Player B
Player A's WoG heals for 1k (7k over-healing)
Player B gains Player A's Glorious Shield (7k remaining).
8k effective healing.

Any thoughts/opinions on the matter?
