I *loved* the changes from last year to this year (and I loved the changes last year from the year before) tons! It almost pains me to even mention two things that I'd like to see improved, because 99% of everything was top-notch and amazing.
1 - The music during specials...for big dramatic things like the battle horns during Siege of the Diamond City or the "attention pathfinders" notes during Legacy of the Stonelords, it was okay...but there were times during Legacy and Bonekeep when some of my players had even more trouble hearing me (or couldn't at all) over a crescendo in the music (some of my players even clapped during Bonekeep when the music got turned way down at one point). I still like it, but maybe doing volume checks during an earlier slot before the special might help?
2 - I'm not sure if this got mentioned above, but I had two tables in a row not fire on Thursday. Fortunately one of my backup scenarios was in need, so I got players, but some GMs for the same scenario as I had ran both slots while myself and at least one other had no players for either one. I know nothing about how the mustering sheets are done, but is there a way in the future to mark which GMs were present but had no players from the previous slot? I'm sure some didn't mind having multiple slots off in a row, but I came to run games and suck players into PFS :)
Again, these are tiny minor things - all in all I loved how everything was organized this year!
