These days I usually just make my own class. What I struggle with (perhaps too much time on hands? ) is what name to give the class. Most of the time, I stick with 'adventurer' or tongue in cheek 'tourist'.
Despite looking at the major/minor skills used for various gamesas classes, I've never developed a good feel regarding what combination of skills really represents the character's profession. It seems counter-intuitive to me that my char would know at the beginning of a game the name of the specific class he wants to devote his life to. I can see someone choosing more generic occupations such as warrior, rogue, thief, mage or sorcerer but other choices seem rather premature to expect knowledge at the time of character creation.
Do you all have similar questions about what to name your customized class?
