I am needlessly whinging, but I do feel a sense of annoyance when reading upon cultivation novels that allows multiclassing but not giving disadvantages such as Total Level Up Limit etc.
Unsheathed and Nightwatcher had similar concepts but the former will force the high end cultivators to choose to mainline being a Deity or Immortal (think of it like Barbarian/ Fighter vs Wizard) at the very end
So take Christianity as an example. The religion remained constant and afloat, albeit with many challenges, from Roman up till to date. It remains clean in a sense.
Then apparently the CN authors has the Dark Souls epiphany and create stories of undying empires, take the above example, Roman.
Rot occurs, both in the empire and in the religion. And yap yap yap.
Might be a fun thing to think about; the skills that have the same name and have similar effect but performs in different manner.
For example, all schools of D&D can cast Fire Ball, except Evocation shoots out one while Transmutation is Roy Mustanging it while Conjuration summons the fire from elsewhere.
An author or some spas changed the book title and somehow becomes a duplicate. One with old name and one with new. And I was genuinely excited to think there's a new work ffs.
