I'm kind of agnostic about the whole thing. Playing 6 the first time through BG1 and 2 was awesome and part of the experience. But I always followed up those runs with small party sizes. I did a couple duo runs, but I never did solo. I definitely never did solo unarmored runs.
It truly seems making 6 an option should not be difficult to implement and still keep things challenging. Sounds more a philosophical decision rather than customer facing.
