Two thoughts:

1) I find it conflicting to both complain that there's not enough to do outside of trick and complain that it's best to hit some bhavas outside of trick. Aesthetically, I don't see why ninki generation needs to result in exactly trick-aligned bhavas; the potency of bhava v. speed of ninki generation and lining up with trick is a separate question (since, for instance, ninki generation could be changed to align bhavas with trick and potency could be adjust to make it DPS-neutral).

2) I strongly disagree that NIN needs more outside of trick. The strength of the class system is exactly that classes can vary along different metrics (for instance, pacing) and players can find the classes that they like most. NIN is a class with high APM in and around trick and low APM outside of trick while having one-minute trick windows. Lots of other DPS classes have smoother APM over the course of their rotations, and I think that the variety is itself valuable to maintain. I'm someone for whom NIN pacing works really well, and homogenizing toward the median APM through the rotation would make the game less fun for me.
