Finally, the implicit assumption that players will be able able to replicate whatever they did in SSS in actual high difficulty content is so asinine that it makes the whole system useless.
I think it should at least be granted that Stone Sky Sea is a good starting point. The ability to reset cooldowns at will makes it way more convenient for practicing the muscle memory of which buttons are where and what order one wants them to be pushed in.

I spent 4 hours at the dummy when I first picked up mch, just picking up the basics. Noting when my gauge was where and how to take advantage of the resources at my disposal.

Did this help first contact with an actual raid? Not in the slightest, initially. But it helped me adapt much faster to the raid because of the Stone Sky Sea practice I'd done showing me the gist of how I want my cooldowns interacting.

Tl;dr: its a single tool. To be effective it needs to be used with multiple tools (like a guide). Even then it won't prepare you for raid very well, but the groundwork is set if Stone Sky Sea is used well.
