EDIT: as I was typing this all up, it looks like people started bring these points up, but I'm going to leave it as is since it covers some aspects not brought up yet, though more needs to be mentioned still.
I'm surprised this hasn't come up yet...so guess I will have4 to play devil's advocate again....
This sort of thing already exists via Conquest Points. And before you say it, they don't have to use THEIR CP to get it when they first start. As stated, they can already find decent gears for the first 10-12 levels really cheap from vendors. It should be noted that this actually continues to around level 20, after that it gets questionable whether it's better to get it crafted or hunted on the AH for something better than the CP gear. You are moving through levels so fast, you only need to update armors and such about every 7 levels or so, and the CP gear upgrades in 5 level tiers via simple crafts (bond an ingot to a harness and it goes from level 10 to level 15, a sheet to mail and it goes from 20 to 25. When the vendor/CP gears aren't available in your home nation (or you don't have the CP yet), you can get a friend to get it for you. not like those of us sitting on 150+ CP really need it that much now.
And that is another problem with this idea...new players won't have the tabs for a while, just like with CP. At least with the CP system, other players can get the item and send it. With the proposed FoV system and making them R/E, it would create a problem by trying to solve a problem--they would need to be maybe Rare, but not R/E for it to work as intended.
Here is a quick rundown of the gear options available to new users/new jobs:
Vendor gears are available at varying levels all the way to around level 40 or 50, forget the exact cut off. But the prices become unreasonable in comparison to the cost to have the gears crafted by someone (used to be available in the AH cheaper) at around level 20-24. However, the lvl 24 Chainmail set is still 50/50 on that front and though expensive is still a viable option to purchase as it can by upgraded for players with a simple crafting recipe to level 36 Silver Mail that is in the upper tiers for defense rating at level 36 (just need to bond silver chains to it, 46 GS cap to make it). All these pieces can be bought/sold via AH/Bazaar, most can be crafted, and some even drop from NM's as well. NPC's bbuy them back for a fraction of the cost, and you are better off posting them on the AH if you aren't going to get a crafter to upgrade them later. Yes, I am bringing crafting into the mix again. A handful of these vendor gears can be upgraded later for better gear--some of it is the gear some of these users are looking for on the AH, and are made by simple recipes like applying 2 lizard
skins to a level 7 pair to leather trousers (@500 gil from NPC) to make a level 17 pair of lizard trousers. This particular example only has a level 18 leather craft cap, and can be made as early as level 8 leather is made (with difficulty), but reliably at level 15 leather--you will get lizard skins while xp-ing during the early levels in dunes (11-14) if you go there, so this can be essentially a free upgrade if you know a crafter.
CP gears/weapons are available starting at level 10, and can be purchased as low as 1000 CP at rank 1. Most all the items in the first 5 rank levels, again, can be upgraded via simple crafting recipes to cover intermediate levels to carry a player through to the next tier: 10>15, 20>25, 20>34, 40>43, 50>52. As you go up in level tier, the rank goes up by one and the cost doubles from the previous tier (level 10, rank 1, 1k CP> level 20, rank 2, 2k CP, level 30, rank 3, 4k CP). These pieces can be traded, delivered, bazaared, and auctioned, and I think the NPC's will buy them from you as well.
Allied Notes Gear. While this is not so much directed at the new players, it is an option for exisitng players that have been doing campaign and are taking a job from 55 up. however, SOME of these pieces are just labeled Rare and CAN be traded, bazarred, and sold via AH/NPC's as well--so older players CAN get these for new players that have made it to 55+ and are having trouble finding gear. There is no Conquest Standing mechanic restricting access to these pieces--only rank (medals for campaign). If the item is not from your allied nation, you just go to that nation and pay a higher price to get it (1.5x markup). These gears comne available at level 55 and Stars/ medal rank (5th evaluation and up), and some peices cost as low as 7,000 AN to buy if in your allied nation (10,500 if not). These pieces are staggered in level and cover all the way up to level 71. They do not have any crafting recipes to upgrade them, but some of the lower level pieces are still reasonable pieces to use as high as level 75 at least as swap-in pieces for situational use.
In the beginning, no one knew ANYTHING about ANY of this information and had to explore and discover it on their own. As things were discovered, sites started cropping up to share the information--first in Japanese only sites, then eventually in English. Now, there are countless sites with all this information out there and can EASILY be found by googling, but if anyone asks in a group, chances are they will at least get pointed to the FFXIclopedia site. Another site is Alla--which has great lists (although slow) of all gears available by job, grouped by slot, and listed in order of level:
http://ffxi.allakhazam.com/dyn/items/job.html
This shows the level of the item, it's stats, and whether it is purchaseble, crafted, quested, dropped and which zone to get it from if it isn't a crafted only piece. You can click on the item (I right-click, open in new page--faster researching) to get all the details on the item's acquisition.
In short, a system IS in place to cover these issues. Granted, it isn't easily known to a new player--but then again, it wasn't in the beginning, but IS now readily available online for all to see.
