Ye, not seeing any mechanics, autoattacks or casts is clearly intended way to clear a savage boss."Hey buddy I know this way how to make a billion gil in ten seconds, but it's really hard to do and takes some skill, it looks very funny too so people will like it, so it's okay right?"
Imagine watching a stream of savage prog, and all people do is trying to spin the boss perfectly until they get the 100%-0% spin. Very good.
