I'm sorry, I stopped reading when you said "healing meters."
Let me clarify. Holy pallys crank out more hps than anyone. And we do it for longer than anyone too (spare me your 3.2 insults). Val'anyr cares not about overhealing.
If you and your holy pallys are reading the healing meters, I really feel sorry for you all. If you're reading the overhealing meters and are sad that your holy pallys are topping it then you should re-familiarize yourself with the proc from Val'anyr. And if your pallys aren't topping the overhealing meters then cut them loose because they're not doing their job.
