Using housing from SWTOR as base for the housing system.

[Jojoya]

Why not just use WoW as a base?

WoW's housing now already can do almost everything what Wildstar and SWTOR does, and it's also a good balance between community and private instance.

Including every item not limited to physics and scale.

Depends on which aspects of WoW housing you want them to emulate. If you're only referring to acquiring a house and the controls for item placement/scaling, I'm on board. The rest of WoW's housing system is at best not an improvement compared to FFXIV and in some aspects is considerably worse. Far too many decor items are gated behind quests, achievements, and rep grinds from old expansions. Sure, you'll have a house but is it worth it when you're limited to decorating with a limited selection of vendor basics and the gold cost of those basics adds up quickly?

I disagree that WoW housing does anything for community. WoW Neighborhoods feel just as empty as FFXIV wards if not emptier because of the spacing between plots (I've got a house next to a friend and we usually can't see each other when we're both on the outside of our respective plots). You can't get into a Neighborhood unless you're in a party and the party leader has their house there, or you have a Battle.net friend that owns a house there. Endeavors do nothing to promote player interaction within housing since most are completed solo outside of the Neighborhoods, not in them.

Speaking of that, I watched the recent ESO stream (never played ESO) and they talked about having many issues that we also have in FFXIV. It's interesting the sheer crossover in problems that they've all had, such as item limits, inventory issues, homogenization, formulaic patches, etc. These MMOs have all been through these things at some point, or are going through them still, the complaints in these other MMOs are so familiar.

WoW housing also has those issues.

Here's an example - for exterior placement you're allowed a budget of 200 points. Each decor item has a value that's between 1 and 5 points (for now, they've hinted at items with higher point values being added later in Midnight). Trees are always 5 points, bushes can be 3 or 5, flowers are 1 or 3, benches are 3, tables are 3 or 5, fountains are 5, etc. The first day of early access, players were already complaining in Neighborhood chat that 200 is too low of a cap because they had barely placed anything before hitting it. Do the math and you see why. If you're using larger items that have a 5 point value to fill up the yard, that's only 40 items you can place. I did mess around in beta using mostly 1 point items with about a dozen 3 point items and got the yard filled up but it left the house looking like it was in an abandoned grassy lot in one design and a junkyard in another.

For interiors, you've got budgets for rooms that can be added in addition to item placement. Different sized rooms have different point values as well. The interior limits can be upgraded by ranking up the house through acquiring uncommon quality or better decor items for the first time and doing Endeavors but that's a slow grind. That same ranking system also adds in new room shapes and sizes as you go.

Want to use multiple of a decor item unlocked through a rep grind and purchased with a currency other than gold? Be prepared to spend a massive amount of time grinding through old expansion content to get the currency even if you already have the rep. Want multiple of a crafted item? Be prepared to spend several hours out farming wood that is Warbound unless you want to pay thousands of gold on the AH to have the crafter farm that wood instead.

Long time WoW players may appreciate having the housing now but it's will be a hard sell to those that don't already have several years invested in WoW, or that aren't prepared to invest most of their time into WoW going forward. As usual, Blizzard took something that could have been fun and turned it into full time job.
