How in the heck is it lazy? It does explain it. There are high and low ends of any difficulty ranking.

What do you want, me to tell you exactly how hard every technique in each rank is? There's no scale to real life, all we have is how hard it appeared to certain characters. The ranking system tells you what you need to know; E rank is very easy and basic for a Shinobi, A-rank is very hard, and S-rank is close to impossible. And S-rank is the highest rank, so once you cross the threshold into S-rank, no matter how high you go it will still be S-rank. I dunno what more you want.
