EX content and up is all about learning through repetition. You're not expected to remember everything the first few times through the fight, not while you're learning, and not even after you get your first clear. Some fights are more intense than others, but don't expect to "memorize" the whole dance of an extreme or savage fight until you've got 10+ clears under your belt. Yah, some people be like "I had it down pat first clear no problem game2ez", and for them maybe it really was. For 99% of the player base though, we are just like you and WILL struggle to remember our steps throughout a fight we aren't comfortable with yet.
