What part of Blizzard's stance suggests they don't understand you. They understand perfectly, they've said explicitly that what you want is not interesting to them and not worth development time. It needs to be something more, something larger, to be a viable option for their time.
As for RP, I don't understand your problems. I can RP just fine with a pencil, paper, dice and friends sitting around a table. Why do you need your own bed to be able to roleplay? ... wait, don't answer that, I already know.
