Since "always be casting" isn't the healer playstyle, the greatest benefit of stacking SS is wasted (this is why SS is great for BLMs and crap for every other caster).

ACC isn't a bad tertiary stat to help reduce misses while DPSing Coil.

PIE is hardly necessary, but a tiny smidge of PIE is certainly better than a tiny smidge of SS.

Short Answer: Don't prioritize SS as SCH at all. You can lose all of it and not notice a difference.
