Would you like an in-game parser?

Honestly? It tells me that you lack awareness. If, after 900 runs, you still can’t figure out when Susano is casting/readying Stormsplitter, then that speaks to your lack of raid awareness.

If lack of raid awareness is a common reason why people struggle with content, what would be the proper content to train people? Is it better to have the first primals and savage bosses doable without much raid awareness to increase people's confidence and experience, or is it better to require more awareness in casual content (and possibly exclude some people from all group activities) and aim hard content to be only for the experienced? There has to be a piece of content which demands some raid awareness without being overly punishing.

Aphrael, if you set the boss as a focus target you'll see each mechanic being cast. It helps with preparing for damage and learning the fight. In primal fights like Shinryu where there are multiple enemy targets it is useful to position the enemy list somewhere where you can keep an eye on it, because the enemies' casts can be seen there too. As for the dice mechanic, that's actually a debuff you your character and you can see it there before the dice icon appears.
