The podcast doesn't have a transcript, so I can only go off of the thread title, but...
I wouldn't mind the bi-yearly AP's if they were of higher quality, or at least not marketed as something you would run out of the book. Everything that's been released requires more time to prep or fix stuff than if I had just wrote my own adventure based on a few high-concept ideas. They really need to have better quality control, or maybe just reevaluate what an AP should be these days. Maybe AP's should cover a single tier of gameplay, rather than a rough 1-15 levels. Tier 1 AP's are basically the starter adventures that get characters up to 5 over the course of a single story thread. Tier 2 AP's get them them up to 11, Tier 3 get's them to 17, and Tier 4 stuff is everything higher. Not only would it better highlight the whole Tier concept, but it would be modular enough to work with all kinds of campaign groups without require the group to dedicate 6 to 12 months solid to a single adventure "theme." I was burned out of cultists by the middle of HotDQ, and didn't even bother with EE because it was just more cultists. The underdark can be fun, but OotA had me wishing I could experience a forest or daylight or something by level 6. CoS is all gothic, all the time, and wore thin after a few months of play. SKT has made me decide that giants are nothing more than Huge orcs, and not really interesting enough to spend 6 months dealing with -- especially when wrapped around an endless sea of random encounters meant to pad out the experience.
So yeah, I think maybe it's time to shift focus, but that's just me.
