I assume you're reading the first books off Kindle Unlimited, since book 10 went up last month.
What I like in the series is that each arc is well different (except when you stretch an interstellar war over 2 books, 10 & 11). Travelogues, politics (you may be OP, but politics >>> you), and trolling the Sects. And there are so many details that can be blown into full plot arcs if necessary.
(also, if you see a cat offering to train you... say no)
I'm almost done with book 10, and I agree that switching it up a little has kept it much fresher through 10 books than most of the other series. I could really do without the lengthy explanations of every single skill they use in battles though, but I sort of get it too. There isn't really any other way to describe what they do than to just use the skill names, but I still wish he would figure out a way to condense it and skip all that crap. Do I need to know that his [Cracked Phantom Armor] shrugged off the blow a dozen times in one battle?
Also, I feel like early on we were told their skill slots were super limited. Now they seem to have dozens if not hundreds. I understand moving the important ones into and out of their core, but it feels like they now have untold numbers of skills just floating around the outside. Maybe I'm misremembering the explanation, or they go up drastically with level, but it just seems like they have a shit ton now. Which makes battle descriptions even more tedious.
Oh, and I noticed he picked up the annoying habit of "flaring" stuff like that (can't remember if it is Unbound or Primal Hunter, since they all run together) series has been doing for years. In whichever series that one is, he "flares his dexterity" to dodge something, instead of just fucking dodging. I think it is Unbound. Now in Path of Ascension he's "flaring his Concept" and such all the time. To be fair, that makes a little more sense than flaring dexterity, but still, once an author starts using a specific term ad nauseum it starts to grate on me. Like DotF and others having everyone fucking snorting all the time. I'm fucking triggered now by snorting!
I will say, however, that the addition of Shadow/Allie to the narrative has greatly increased my enjoyment of this series, which was previously trending downward like they all do after so many books (expect DCC). She's awesome, and I'd read a series based solely on her.
