Yup. I am of the school of thought that, when RPing, it’s usually a bad idea to call people out as being a particular class.
But then my background is that I played NWN for years before playing WoW, and NWN is D&D. And in D&D, there’s a thing called multiclassing. You can take levels of monk with your cleric, f’rinstance. This helps to muddy the waters a little so that people aren’t tempted to just call people by their class names. And among the people I played with there was an understanding that you took levels of classes that represented something of the background of your character, but you couldn’t assume that, say, all Bards were the same kind of character.
