I enjoy PF. There are a good number of issues with the system, as there are with any system, but overall I have a good time playing the game.
That said, the ever increasing rule set is getting rather cumbersome. While this is not an issue for home games (where most folks I play with look at the rules as a set of guidelines ... with the occasional quick rules debate), it is certainly becoming an issue for PFS, at least from my point of view. The errata which result in requiring character rebuilds, the ever growing list of PC classes and archetypes, and the ever expanding FAQs are making it more burdensome to run PFS for folks who GM.
Does this mean I will stop playing? Nope. When I play or GM I enjoy myself, primarily due to the folks I play with. Occasionally I will end up at a table with a lackluster GM or a jerk who has his or her PC act like a jerk "because it's what my character would do", but those instances are thankfully few and far between. Couple that with the fact that the folks I play the home games with are also willing to pick up a game of Shadowrun, Star Wars, WoD, etc etc etc and if there is an increase in a burnout level it can be countered easily.
At least that is where it stands now. Ask again in a year or two and we'll see how the weigh of the rules looks at that point.
