I’m curious in the AP line, what books 5 & 6 did your group find challenging?
For my group only these books were challenging:
Kingmaker books 5 & 6 (certain parts were easy others were challenging)
Carrion Crown book 5
Reign of Winter book 5
These we played and my group found them to be cakewalks;
Curse of the Crimson Throne book-5 (with Pathfinder conversion)
Carrion Crown book 6
Jade Regent book 5&6
Skulls and Shackles books 5&6
Reign of Winter book 6
Wrath of the Righteous books 5&6
My group is burned out on AP’s and the primary burn out is centered around the AP’s being cakewalks at higher levels. I don’t have the time or the motivation to make heavy changes and/or re-writes to the upper level books so I am looking at what AP’s to schedule to run for my home group with the challenge of the high level books being a primary factor. I already restrict many of the soft cover splat books put out by Paizo and follow PFS character build restrictions to limit character power.
I’m looking to tie authors to challenge levels since Paizo leaves it up to the authors to play test the scenarios.
