So, it is possible that you may be wanting to cast a Penance for a particular GCD, but you're damn near forced to cast PoH as to not loose out on massively wasted DA.
Now, in 10man this would be fairly easy, just PoH 1, PoH2, and boom refreshed until the next damage spike. In 25man, however, that's 5 PoHs just to maintain DA between spikes. You have to darn near start refreshing group1 as soon as you finish casting on group5. It's a horribly inefficient system.
Quite honestly, the developers got it wrong from the beginning. PW:S should have always been 15sec and DA should have been 30sec. It makes far more sense for the cast-able shield to be something you use for planned damage, and thus does not need a huge duration, while the random proc and AoE Heal buffer should stick around, because it is a "bonus" on your heal that is calculated into you're overall efficiency, not something that looks pretty and gets wasted unless you dump another 10-25k mana of inefficiency on it.
