I cannot disagree with this request more. I'm rarely disappointed with the ability to choose my gender/race/species/orientation/etc. In fact, I will almost always choose not to play games that don't allow this. TW3? No thanks. Geralt does absolutely nothing for me. The fact that I have to play as him (and I know why; I get it) makes that series totally uninteresting to me. So, yes, in my opinion, having a bland (imo again) protagonist destroys RPing aspects of the game. I've said it before and I'll say it again. If CD Projekt decides to create a companion game where you can create and customize your character in TW setting, I'd give the series another chance. Until that happens, I'll stick to games that allow me to customize my character.
Plus, there's never been a Bioware game that didn't feature this (even the early games allowed you to pick from a variety of presets), so I cannot imagine any situation where they would stop doing it now. Maybe in a new IP, but I even doubt that.
