When you heal your beacon target at full charges with Holy Light to keep up the charges it keeps saying
< 3 Holy Power>, telling me that after I used an ability that generates a Holy Power, I have 3 Holy Power. Now when someone's health in the raid suddenly drops and I go to use Word of Glory on them because Holy Paladins are more flexible and can do that, sometimes Eternal Glory will proc and not use Holy Power and then I get the < 3 Holy Power > text again.
It's hard to explain and you have to be a Holy Paladin (who has used the floating combat text for energy/mana/etc gains) post-patch to understand the difference. We are very flexible now and can easily raid heal, of course not as good as raid healers but decently, and we are constantly using our instant casts and the Holy Power change for combat text makes it very confusing when you are measuring who to heal with the current amount of Holy Power you have.
In short, it's nice that you made tracking Holy Power easier for Ret and Prot pallies but please re-add the option for the floating combat text to show Holy Power gains and not just Holy Power total.
