If you're a roleplayer, then role-play your character. Think about your character as he relates to his world. Why is he an adventurer? Just so he can die in some far off cave? I doubt it. He knows adventuring is dangerous. He knows he has to bring his A game. He knows he has to make some, preferably many, choices about his training and his knowledge so that he can survive some of these dangers.
So are you saying that optimization could be considered an inherent part of roleplaying, since if you want your character to survive (how else would you roleplay him?), you would need to make him strong enough to handle the threats he is expected to face (if not stronger)?.
Good for you; I have been feeling that roleplaying is dead looking at the number of people who treat it as an exercise in mathematics rather than a game of the imagination. Concept over so-called optimisation is the roleplaying way.
It is far from dead. It just isn't always the only way in which dnd can be played. There is no reason why character concept has to take a back seat to optimization, or vice versa. They can both co-exist peacefully side by side, and actually complement each other.
Which is why I don't understand people who claim that roleplaying necessarily has the come at the expense of optimizing your character. Nothing can be further from the truth!
