Are you serious?
I also made a post about this when S&M were added to showdown a year ago, and the response was that "we don't know what that means in-game, and until we do, we can't copy it!"

It's bad enough that you hadn't figured out the move's effects at that point (especially considering the fact that the move's in-game description gives at least enough information to ease research of the move), are you telling me that in the year that's passed since then you haven't even looked at the move AT ALL? And on the point of irrelevancy, if this was the reason the move hasn't even been glanced at at all, why did you bother to code in moves like Leafage?
That's not all, though. Today I had a battle using Dusk Mane Necrozma with its z-move, Searing Sunraze Smash. In the battle, I used the z-move against a Celesteela using Protect, and the damage was reduced to 25% of its original damage.
The problem is that the move ignores Protect and other protecting moves, and this much is even shown IN THE MOVE'S DESCRIPTION ON SHOWDOWN.
