I, as a self-confessed decent RPer, have come a long way in my games since I was in 7th grade. My whole group has. We kept the same characters for years, and got to see more and more personality develope in them. When we started, we all sucked, but because we had a good GM, we grew and learned. People came and went, but the only time I saw people playing the stereotypes was in that old game. One kid, whom we don't play with now, played a Paladin, every time. He'd attack first, run from combat while the group was stil fighting... He played a priest of war doing that, and the GM took his spells away. He was miffed, and so were we, but we were mad ebcause he still didn't get it.
I went from a Minotaur fighter with no personality, to the devoted defender of the Party mage and leader, who secretly pined after her and wished for nothing more than to mate with her. It never really came up, but it improved my roleplaying to have a reason to follow her every order and whim blindly. That was the character, and we had fun.
(I learned, years later, that the one who played the Mage was thinking the same thing! Who knew!)
The character's class doesn't matter half as much as the effort put into their background and personality. The restrictive classes are good for intermediate players, as it igives you a direction to bring the character, but I prefer the freedom of Fighters and Rogues over the structure of Paladins and Bards. In the beginning, I played Fighters and Rogues because I didn't want to have a class I couldn't keep up with, RP wise. So it's a sliding scale.
Right now I'm playing a Rogue (Fighter Ranger now, but..) who was raised by the temple of the god of justice, who ended up sneaking out at night and leading a double life as a rogue, and who eventually developed multiple personality disorder, so he could have a truthsaying spell on him and honestly say "I didn't do it."
I've found that the longer you play in high Roleplaying environments, the better you will become. We should encourage this in everyone we can, as it's a wonderfully creative outlet. When D&D becomes no different than the computer games, I feel it's lost something beautiful, and I'm glad there are so many avid roleplayers out there.
