I think new and deep minigames would add most to the game. Think GW1 Polymock expanded and with also a competitive side. Or some form of card game or brawl with special skills. Most of the other points really would not be an expansion seller for me:New Playable Race: As much as I'd like to permanently bounce around as a Quaggan, I definitely would not play a copy of a profession I already have nor racechange one of my own.New Profession: I'd rather have well fleshed out e-specs than another profession complicating balance even more. And really the difference is not that huge.New terrestrial Weapon types: I think that's more of a sub-point of new e-specs once they start running out of options. Seeing as A-Net is bringing new "weapon types" out of the old ones (Staff as Battlestaff or Scythe) this is probably the better option.Player Housing: As others have already said: This would probably be super expensive, require scribe or some new discipline and be a gold mine for the gem store. And I'll 100% pass on another WoWesque farm or garrison that wants daily attention from me.Return of Dungeons: Seeing that fractals are the new dungeons and they are doing a decent job at it and offer a more open advance instead of the fixed dungeons with paths, I'd say stay with that. But I'm really no fan of speedrunning dungeons anyway.Return of Hardcore World Bosses: Just no, this would rather turn me away from the game. If you want challenging group content, raids are the way to go. Open world should be casual with meta events like Tarir that can be coordinated with Commander tags and have no hard failure requirements. Who really wants more world bosses that you have to be 30min+ early, join some TS and then still have a decent chance of failure?
