I guess it's no surprise that no one has mentioned my favorite class. I'm not kidding when I say that for me it is the fighter class. If the level cap is high enough I will certainly mix in some second class, but fighter is the most fun class to play for me. In second place is ranger (just for the pet), and paladin third. I only have an interest in playing melee-martial classes, and will add in some spellcasting class only as a possible secondary class, for example fighter-sorcerer or ranger-cleric.
