I am entering the second book of WoTR and I am looking at the skill DC's and the current level of skills my PCs have. Did Paizo break the skill checks by adding the +3 to skills that your class is trained in?
Do I need to bump skill DC's way up?
Skill checks are meant to be succeeded. If your PCs are succeeding at them...good.
More specifically, your PCs should need no more than a 10 to get an average DC (Diplomacy for certain NPCs being a good example).
If your PC is hyper focused on one skill, lower that to a 5, and don't be surprised if they make many checks on a 1.
This is working as intended. If you're spend resources on a skill, you should be good at said skill.
Skill checks in APs are not generally meant to be an "Oops, nobody rolled high? Well too bad, guess you're not proceeding". That would be poor adventure design.
On occasion, they're set just high enough (at later levels) that if nobody has invested in it, they can't get it, but usually this is for checks that are less important. For mandatory story progression, other options are provided.
