I feel like Blizzard learned the wrong lesson from Garrisons

The lesson they appear to have taken to heart is that "Player Housing won't work/isn't what players want/isn't good for the game".The lesson should've been Giving players an entire goddamn town to themselves full of every town convenience and function and full of resources is a bad idea.Despite the doomsaying and Negative Nancys on the subject for WoW....Player Housing/Guild Housing has been perfectly fine in nearly MMO it's been implemented in. It's certainly hasn't destroyed WoW's two biggest competitors - FFXIV and GW2.And that is because they follow two basic rules; it's not allowed to replace functionality of towns/interacting with other people and it must not be a replacement for socialization with other players.Or, TL;DR - Cosmetic Only, you still gotta go out to to talk to people.Follow these two simple rules, and there is no reason Player Housing would not be a huge boon to WoW, nor is there any reason why it would destroy the social aspects of the game. Executed properly, it also becomes an encouragement to try new and harder content; after all if you want that sick decoration for your house, you'd better put up and do Normal/Heroic/Mythic raids. Or master Pet Battling. Or start burying fools in Arenas etc.Or working together with other professions to build furniture etc. AND it gives Blizzard another lever to work the economy with.
