There's no way to tune difficulty for everyone since it is subjective, but this is a certified git gud moment. Portraying the battle events and mechanics as unfair or random is dishonest. Not only do most bosses in dungeons, trials, raids so far show you what can happen with a simple version of a mechanic before showing you something that can kill you; but everything is far more intuitive for first timers. Everything uses simple shape and color queues, and the rhythm is easy to pick up so you know when a time to cast a raise in a lull. This is the most satisfying that normal/casual content has ever been.
