1) If airships are added, the distance between cities becomes normalized. The current dynamic of Ul'dah being favored because it is in the center of the linear path becomes diminished. Hopefully this will reduce the 'over-centralization' of a single city like Ishgard.
Agreed
2) The locations of the crafting guilds in various cities (and presumably NOT Ishgard) promotes crafting of the appropriate types within the correct cities. I suspect that as time goes by, more of the more advanced recipes (darksteel, anyone?) will require tier 3 facilities, thus requiring crafting within the appropriate city. This effectively creates more demand for certain products within those cities.
Agreed. My thinking with the tax system revolved around this fact. I wanted to discourage players from selling items already available in the cities with crafting guilds.
Ex: If Buffalo Leather Spetch is sold at the Leatherworking guild in Gridania for 1600gil, I wanted traders to rent stands in Ul'dah or Limsa Lominsa if they wanted to deal in Buffalo Leather Spetch. That way the item is available on the local markets with no mark-up, as well as the World Market with buyers paying extra tax to balance the convienence- and players in Gridania would only buy the Buffalo Leather Spetch from the player economy if the free market had driven prices below the NPC price in the guild.
If retainers could more easily be placed within the market area of your city of choice WITHOUT the need to travel there (see previous suggestion for NPC linkshells for retainers), supply could be made to more easily match demand.
Ok, wow. Your last suggestion about retainer linkpearl just hit my like a ton of bricks.
c) Still later, allow direction of retainer to a specific Market Area without having to "hold their hand".
YES!
3) There are high-level areas all four 'citified' zone. Coerthas stands out simply because it is missing the lower level content (monsters starting around rank 20ish), and gathering nodes of only grade 4 and 5. Heck, there are rank 65 sundrakes practically within walking distance of Ul'dah. Hopefully these high level areas will have high-rank content to go with them, and so this content will be well distributed throughout the continent.
Agreed. All I could add to this point is a quote taken out of Letter from the Producer V
The people have spoken. As such, we'll be operating under the premise that new PvE content, such as dungeons containing sought-after loot, will be instanced. By instancing content in this way, we'll be able to reduce claim wars and counter-camping and all that. There's also the added merit of enabling the level design team to work with a clear theme in mind, and create much more engaging and challenging content.
4) Grand Companies will be present in at least the three cities of Gridania, Limsa Lominsa and Ul'dah (listed in order of my personal preference ^_^), but may not be present in Ishgard. Perhaps some other mechanic will take place here, since there seems to be a more 'warlike' vibe to Ishgard, as well as the small keeps surrounding it. Activity around the Grand Companies will draw people to various cities, thus upping demand in those cities.
Another quote from Letter from the Producer V
Also, the solo play response for farming/gathering is extremely valuable feedback for the dev team, and I’m thinking that this is something we can tie into the in-game companies we have planned!
