I was arguing that it *could* be - and that if one were doing so, one might choose a less-than-optimal build.
You can choose a less-than-optimal build without representing a "real person" either. You can perfectly build, and roleplay, a gnome barbarian with only one eye. It's far from optimal build, but it might be fun as hell. My point, though, is that you shouldn't roleplay him as if he were an Ohio Plumber, you "should" try to play the role of a one-eyed barbarian gnome. You should build *his* personality, and try to act as *him* (some characters will be harder than others, for sure.)
I wasn't arguing with you, nor I was advocating for (or against) optimization. I was quoting other poster (Ahnehnois) about his definition of roleplay, based on acting like "real people", because I feel you should play the role of your character, not "real people". If you pretend to be an elf, or a gnome, or an alien cyborg from outer space, you should (imho and all that stuff) try to act like one of them, not like a plumber from Ohio. It's just something that irks me, I've a player in my group that always act out the same, whatever his character is. He plays as what *he* would do, instead of what *his character* would do. No matter if he is playing a Paladin or a Necromancer. I find this not to be *role-playing*. He is playing, and if he has fun, more power for him, but that's not to play "a role".Let me be clear - If you are arguing with me because you think I'm trying to knock optimized characters, stop.
