Don't get me wrong. It is not that the AP itself is bad. It is that I had done something entirely different with the Compagnon. It was a noble thing, a force for good. Having it be what it is described in the AP... It would simply not pass with my groups.Our DM cut all that nonsense out after he saw our reaction to Candlekeep. I'm glad he did that.
I have to second your pet peeves. One guy has no interest in anything so the whole time we drag him along (ugh).
Now if you will excuse me I am going to look through all the “modules” In yawning Portal!
One more thing I'll as as "badwrong" (for me of course): trying to be better than the other PCs. I.e., always trying to outshine with with everything from a mechanical standpoint. When I see a player doing that, and getting upset as if it's some sort of competition between players on who has the most optimized PC, it raises red flags for me. If one PC gets a magic item that gives them an extra +1 bonus to such and such, and if you get really upset because your PC doesn't get an equal bonus right away, my warning bells start to go off.
The DM trying to tell me what my character would or wouldn't do.
The DM describing what my character does or thinks when narrating the results of the adventurers' actions bugs me as well.
