Ok! I gotta ask, you were on these forums before to complain about badly written adventures and the work you had to put in to prepare them for use, this was about WoTC adventures and now you are making a similar complaint about Pathfinder APs. So, why are running prewritten adventures if they are not making your life easier?IMO, those claims are vastly overstated. 5e is probably the least accessible to new DMs of any edition I've played since I began in 1989.
I'll count the ways.
1. Largely terrible prewritten adventures.
2. No meaningful guidance for treasure awards.
3. Awful encounter building guidance.
4. Meaningless tactical options.
5. Befuddling action economy.
6. No way to address PC power creep.
7. Black holes in rules content.
And yes, some of the older editions had no guidance at all for some of these issues, but I'd argue that no tool at all is preferable than a broken tool.
Now I do not know if you are posting just to vent and advice and commentary is not welcome. If so feel free to ignore the rest of this post.
All AP style adventures have similar issues in that the party has to meet the DM half way but I regard that as part of the table social contract. If the players want a sandbox they should make that clear.
I would really recommend the book "The Return of the Lazy Dungeon Master" by Mike Shea, the best book of DM advice ever in my opinion.
