My issue with StarClan is that they can never stay consistent. It doesn't matter what arc, what super edition, what book... nothing is the same. Especially with a lot of the elder, wiser cats (Yellowfang, Bluestar, Whitestorm, Lionheart, ect) in StarClan. While these cats were alive, we didn't see anywhere near as much of these popups from the Dead Starry Cats.
The Prophecies Begin --> mysterious, vague, doesn't say much, prophecies actually require some thought to a point
The New Prophecy --> appears more and more frequently (I presume because of Leafpaw/Leafpool), still a bit vague, but nowhere near as lesser-known as the original arc, at least one prophecy is obviously misunderstood due to Cinderpelt... and I'm not even sure if she really consulted Leafpaw or not
Power of Three --> way too frequent, constant viewpoints, StarClan cats butting in every couple chapters
Omen of the Stars --> Even more frequent than Power of Three, viewpoints are still very much there a lot to the point some of these are getting full chapters to themselves
Dawn of the Clans --> StarClan here was a lot more vague, and while they appeared much, they seemed to have shifted back to the StarClan we knew from the first arc
The prophecies from Power of Three and Omen of the Stars were literally spelled out, and made obvious as hell to the reader, especially the ones from climax of the fourth arc. It was made glaringly obvious that Firestar would play a huge part in Omen of the Stars, and that kind of annoyed... especially because it basically tossed the Three back onto the sidelines, while Firestar did all the work, battling with Tigerstar. Dovewing used her powers...maybe a small handful of times for something useful, and the rest was just nonsense. Hell, Firestar being the fourth was utter nonsense too- Ivypool did much more than he did, and she just got cast aside in favor of her sister.
A horrible thing with StarClan and most of the writing.. is that they treat the cats like they're days-old kittens- so many of these prophecies could be much more mysterious and vague if they'd stop making it obvious which cats they want involved.
