I’ve skimmed the article and haven’t read it closely yet, but so far, the only thing I’m not for is the BMAH portion. If having my house publicly open turned out to be something I wanted that badly, I’d find dealing with the BMAH to make it happen deeply irritating.
I would want the option – just as a toggle, not as something I have to bid for – to open my house to party members, raid members, and my guild.
I don’t think this would be an RPers-only feature at all, but even if it were, that’s a pretty valid thing for an MMORPG to dedicate resources to, especially given that RP is in the name. Lots of people don’t raid; lots of people don’t PvP; lots of people don’t do Mythic+. Those are features developed and maintained for segments of the playerbase, and RPers are a segment of the playerbase too.
Also – I think in-city districts for ‘basic housing’ (just a rented room, for example) for an extremely low buy-in would be a good idea, but I do not want capital cities to be the only housing location. Other zones’ housing plots might need to roll out over a few patches – maybe even more than one expansion – but I refuse to believe that having housing plots outside the capital cities is too much work for Blizzard to accomplish.
