I'm sorry but the normal raids definitely are. M1 has very clearly choreographed half arena and cone stuff, with the checkerboard thing that is also pretty easy to understand, the knockback might get you once but it's pretty simple past that. M2 is a bit harder but outside of the heart mode where it's just dodging it's very easy. M3 is really easy, and M4 is cool but quite easy as it gives you a lot of time to react, the clones are very readable after you see them the first time. You might be thinking about it wrong, because a pyrrhic victory is way more satisfying and fun than an easy clear usually, and from the sound of it you were clearing first try?
