SOME THOUGHTS and IDEAS
Dear Blizzard-Team,
as many others, i really looking forward to the new housing feature, even if many, me included, are somewhat nervous about how you will implement it. Your choosen design pillars are good 
I want to share some throughts and ideas i had over the years. I think, many of these ideas are already on your table and i also think, that some ideas are already set, but will be on a developement schedule for coming expansions/seasons etc.
Two areas are very important to me, when it comes to housing. As a pillar you have the social interaction, which only will occure, if there is a reason for it. The idea of common goals for neighborhoods is one way. But, …
I would love to have a reason to visit my friends houses on a regular bases. So here is IDEA 1:
- Seeing how my friend or guildy did with his home is one motivation to visit them, but i think its not enough
- But what i would do on a regular bases is, if i could use my friends/guidlies profession skill in his home. A small implementation of this could be, that personal crafting orders have to be done in the home of the people. More advanced would be, that a person could pre-produce items and i can go there and exchange them via their crafting materials or gold, until his/her stash is empty.
- The idea, that i visit the home of a person, which i found via the trading chat, to let craft my item would be also somewhat cool.
Idea 1 needs a easy way to get to specific neighborhoods and also to travel between different ones. And this brings me to the second idea.
I think, one major let down for many is, that we will get only a human and horde themed neighborhood at the beginning. Many want to express their character fantasy through a fitting home. I would think, that this is one feature you want to develop over time, also that you have new content in the future. But i also think, the main start races should have their themes (human, orc, dwarf, elves, tauren, trolls, undead). In the future, you can add new themes fitting the various areas of a new expansion (for example Hallow Fall, Dornogal, etc.) so there is plenty of potential. The other argument you had was, that if there are a lot of different neighborhoods, players will get spread out. This is a bad argument, because neighborhoods have only 50 slots, so there will be a lot of sharding which means a lot of parallel neighborhoods either way.
IDEA 2: Make more variations of neighborhoods (at least 4 for the start, with night and blood/high elf themes fitting the midnight expansion) and interlink them via a Stone circle portal area with big portals, through which you can see their themes, sizes and names on top, and which allows for quick travel between them. Add also neighborhood partnerships, where guilds/communities can link various neighborhoods (by name) with each other. This will solve the problem of big guilds with more then 50 players. With this function, you can also automatically place portals of neighborhoods, where people build new homes for their various warbands. I can imagine, that with the new warbands feature, where we can have various warbands, we also can have multiple homes, one for each warband? Because i would love to have a nice orcish home for my Orc Shaman and a cozy nightelven home for my nelf hunter (preferable near the new world tree on the dragonisles).
I know this is a big step for blizzard and i hope you do it the right way without shortcuts. Because, if you can manage to get it right, this will be a feature which will bring many people back to wow.
