have been lucky to NEVER EVER had a player want to be a monk in any of my FRG campaigns in 40 years and OMG I hope to continue that streak. I find no room for the class in my world view and would love to keep it that way. (this includes a half hearted attempt to run an Oriental Adventures game but everyone wanted to be a ninja)
I have played in others games where Monks were played including the 3rd ed broken ones with vows of poverty to cheese up powers. They have their place in Eastern or pulp settings but they like all the Eastern classes seem to clash with High Fantasy archtypes
