Using your burst cooldown with macro every time you use your main damaging ability without any way of controlling is a failure.
Ferals a highly mobile and switch between targets almost instantly. Sometimes they build combopoints and use a finisher just to activate instant cyclone. What kind of switching and burst can you have if you waste your cooldown on secondary target all the time when you build combopoints?
Again - I don't care about you and your playstyle. It's your personal business and I don't have any intention to interfere with it.
But giving new players advices like this is really, really bad thing to do.
