After a certain point, you simply need stronger skills and lower CDs more than you need more skills.
Your whole post was good, not saying I totally agree. But the last sentence is sort of the Cliff Notes version wrapped up in a sentence.
All or most powers scale, so the first Flare you get, gets stronger as you go, correct?
So that makes hybrids totaly more viable, if they didn't scale, it would kill hybrids mostly.
But the big point is, yes you need to figure out what skills you want to cover the bases, more than that isn't needed and then you are best getting AP up and CD down.
The game is pretty darn good in combat, you can stay focused on a few and really max the ability in terms of power, AP usage and CD. Or you can sacrifice some of that for having many more tricks in the bag. Since the game imo, once understood isn't terribly difficult, you can easily go with the more "tricks in the bag" approach for diversity/perhaps fun if you like and still have a great time.
