Let me try a different approach here.

Normal Raid/Trial = A forgivable window for learning telegraphed mechanics and ample opportunity to recover from mistakes.

Savage Raid/Ex Trial = A hidden list of hundreds of actions that must be performed in precise order and with perfect positioning. Any mistake by any player results in failure and starting over from the beginning.

I really don't see where I'm wrong for thinking this is too much of a brick wall. It doesn't feel like difficulty, it feels like psychotic fake difficulty.
