So I'm finding these now and I still think the pace is completely off. You get a single technique early on that has 10 levels and is quickly maxed, then you get none at all for a long stretch and then you get 10 at once each of which has 100 levels and basically needs to be leveled with an autoclicker because there's no passive option. I'd expect something like a "Meet the Charge" technique from the Guard Barracks or a "Willowbrook Blade Form" from the sect to fill the space in between.
The game also becomes less passive as time goes on. While early on you could just level a skill for a few lives, now you have to be there to do a time-sensitive rotation every time before you unlock the ability to actually level the things you're working on.
