One of the reasons I like 3.5 is because of how classes can defy the standard expectations of their role. Take your humble cleric. Usually considered to be a healbot who occasionally hits the enemy upside the head with a blunt trauma weapon. Now build it differently and you've got a holy warrior ready to lead an army against the forces of darkness. It's all in the choices you make for your character. Also it amuses me to challenge people's expectations of classes. Especially ones that are supposed to be backup or "boring.
