I mostly dislike spellcasting classes in my game, as it is one of those "Low Magic campaigns that suck"
I'm pretty stingy with magic items, which tends to really,
really ramp up the spellcasting classes effectiveness (As they get to choose a minimum of two new spells every level).
I mostly like games about barbarians, fighters, rogues and my own variant ranger and variant cleric. There's no place for Monks, and preciouslittle for Paladins (though there are NPC Paladins...they are a scary order that hew a little closer to "Law" than "Good" unlike the standard D&D Paladin who seems to pay more attention to Good than Law as a rule).
All of that said, I would never bother allowing someone to play a Monk just so I could screw them over; though I've lost count of the people who want to play a spellcaster "for RP reasons" (Bull




)...they always seemed to hear the words "low Magic" and decide that they needed to screw with
me by playing magic-based characters.
