It's just luck of the draw. 3 arcs is a very, very small sample size for drop chances.
The worst droprate that I've personally seen was a run where we stopped at 5-1-1. In that run, I got 1 page and my partner got 0 pages, for a grand total of 1 page for two players in 4 full arcs.

These second of these two runs, BTW, was just one day after the first run.
So, as you can see, there can be pretty wide range of results. Which should not be surprising since when dealing with such small number of drop chances, random variation is expected to be pretty high.
Definitely agree that it could benefit from being boosted. There have been quite a few days were both my partner and I get no pages, even with doing all of the side content, scamps, and marauders. Just making the pages cheaper from the vendor, even if it's just a few thousand cheaper to like 8k-10k, would be nice, too.
Still waiting for answers about class set aura behavior, and also hoping that one day hair dyeing will be an option. We know it's canon thanks to a book in the Manor of Masques! (House of Reveries: The Troupe)

I played to Arc 3 yesterday when it released on console, killed 2 Marauders, secret rooms and treasure goblins.
Didnt get 1 page but low drop rate is understandable since Zos probably wants people to spend their Archival Fortunes.
I've gotten 5 of the style pages so far in about 10 hours of running archive (on various classes, sometimes just doing 1 arc for the daily, sometimes doing more).
