I actually get a bit annoyed when SCHs use stoneskin in casual content and barely touch Adlo for some reason. There is only limited utility for them to use SS. My favorite is when you have two healers scrambling to cast pre-pull in instances like Bismarck EX. It's a waste, unless you put up Succor too as they all will break once the island gets hit in the pull. To negate what? Chump change damage. Only the tanks end up keeping them intact so why bother.

I was running WAR in the vault the other day and this one just kept using SS on every pull. I'm like is this a WHM trapped in a SCH body or something? It was rare to see an Adlo. It wasn't needed either since I use cooldowns often, but if it gives someone a peace of mind.
