When should WHM use Stoneskin I?

Just figured I'd throw out some food for thought for some advanced techniques when you hit 50. There are some attacks in the game that reduce the healing efficiency a target may receive. This debuff is generally known as Infirmity and most notable users of this are Twintania's Death Sentance in Turn 5 and the final boss of Stone Vigil HM (I'm sure you've had experience with both of them). Single tank Ramuh EX comes to mind too.

Also Levithan EX and Briny Mirror is another example where regen and stoneskin can help mitigate without adding stacks.
