It is pretty disheartening to see the creative director basically stick his fingers in his ears and say "lalala it's the gms fault not ours" every high level adventure 12+ needs massive tinkering to not completely fall apart from my experience. this is from someone who has been running D20 system since it came out, you have to try hard to NOT break the system.
It could SOMETIMES be a case of inexperienced or bad DM's but not acknowledging the glut of terrible problems high level play has and addressing them in the adventure design (make the battles harder) seems to give off a "I don't give a crap people will buy this stuff regardless" kind of attitude.
"There are no problems everything is going according to plan"
*SIGH*
I love the adventure paths (greatest rpg idea ever) but there is big room for improvement in the back halves of these paths, not even seeing a problem is really disheartening.
