OK, just the comments page 1 because I don't have much time now. Apologies if Scott has mentioned the same things already.
Header - The title is missing
If you are using British English, then it should be -ise instead of -ize.
Extra pieces: The official carcassonne rules do not define what is (1) neutral and (2) meeple. If you are going to use either or both of those terms, you'll have to define what they are. Note that meeple isn't a word in standard English (neither American or British).
Apparently "disc" is used for musical disks - i.e. CDs, phonograph, etc. A circular flat piece is a dis
k. I didn't know that until I checked it out a while ago.
Play a tile - wait, there are tiles in this expansion??? I don't see any in the Extra pieces section. I'm confused.
What is a cathedral tile? If I run out to my local cathedral in the middle of a game and paint some graffiti (i.e. draws) on one of the tiled roofing, can I claim the missionary?
It might be better phrased as "a tile that depicts the cloister, shrine or cathedral"
Question about claiming the missionary - if it is already in play, can it still be claimed? Or can it only be claimed when it is not in play? The rules doesn't state this clearly.
"place it on that feature with the disc of his/her own color under it " - Don't you think it would be a bit unwieldly to place the disk under the tile???
I like the idea of a missionary feature. What exactly is it?
What exactly does the missionary-as-monk do at the shrine place? Can someone still place a heretic on the shrine place?
Footnote 2 and the first sentence of preparation says the same thing. I don't think Footnote 2 is required.
Who is the "My" in the Footnote 1? Is the rules document being personified? Or would it be better to use "It is suggested that..." instead?
What exactly does footnote 5 refer to?
There's a bit of a blank space between the Deploying and the Scoring sections.
