Greetings. I hardly ever post here, but after a lot of the various discussions around the community concerning mods - from their existence to the problem of people taking pictures of others with certain mods on without their permission - have lead me to come here to propose an idea that will not only help SQEX, but also help modders.
Although it's largely underrated, EverQuest created something called the Player Studio in the wake of EQ Next being developed. It's something that still exists, for use with EverQuest, EverQuest II, and PlanetSide 2, so people can take a fuller look at it via the link above; the link leads to a page that gives a short explanation of what the system is, with links to FAQs, Style Guides, and the Player Studio itself.
The general gist is that the Player Studio allows players to download various geometries from any of those three games, then allows them to build custom items from those geometries. Once created, a player can upload them to the system, and players of the game the item is made for can purchase them for digital currency that is bought with real world money (think Crysta, but for EQ/EQ2/PS2). The company gets a cut, but so does the person who made the item - so it would allow modders to monetise their works without violating any rules.
I believe that many of XIV's issues with modding could be "fixed", so to speak, by implementing a system like this into XIV. It would allow modding to "come out of the shadows" while also giving SQEX control over the system, while both parties make some money from it.
Like Skyrim, the XIV modding community has some really good artists in it, and many of them deserve more credit for their work, and deserve to be paid for the time they put into making their mods - something this sort of system would do, easily.
Granted, there are some mods that wouldn't be found acceptable, but the vast majority of them would qualify for being put into such a system.
There's one grey area on this whole issue - mods that make NPC clothing and hairstyles available to players. I think there, SQEX should allow any hairstyle that they aren't going to put on the Mog Station to be handled by the players, however if they plan on releasing something on the Mog Station, they can reject the item. Blanket banning all NPC items isn't precisely a good idea, as it could save the SQEX team a lot of time (and hence, money) if a modder made something and put it into the system. Conversely, SQEX does need to keep certain items available as Mog Station/SQEX exclusives, which largely are holiday items and NPC sets.
Of course, getting SQEX to make such a change would require getting a lot of the player base on board with it, so even if you don't have much to say about it, please post a response if you support this idea.
