I feel like you are missing his or her point. It is very common practice to break things into easier to digest chunks. That is how I learned to play the piano. I'd learn a piece by breaking it into...well, pieces, and then build up muscle memory for each one, until I could put them all together. SAM, for example, revolves around 3 basic combos that build up sen. Learn combo 1 and its nuances, learn combo 2 and its nuances, then learn combo 3 and its nuances. Your rotation is now easier to understand. I'll do combo 1, combo 2, combo 3 and then my sen finisher. It also makes it easier to adapt, as it's not always as straight forward as one combo after the other.
Not everyone likes that, and I'm not saying that you should have to like that, but your post reeks of vitriol.
