That's not the actual specific thing I care about, in the title, it's just the easiest term to bring together some ideas as an example.
Processing is supposed to take time and 'fuel'. Supposedly both of these are important. How important? I don't know. But let's assume something between BDO/FFXI and optimized MineCraft, but not all the way 'down' at unoptimized MineCraft.
Freeholds have processing stations. This is not a complaint about how Freeholds work, but feel free to add some!
The question assumes that only one person can use your Processing Station on your Freehold at once. It is also assuming that some number of people other than 'unlimited' can use the Processing Stations in Nodes, at once. Hit the spoiler Tag for some data if you're not familiar with some things. Note that EVE and SW:TOR are not quite equivalent. I'm aware of them, though.
Unoptimized MineCraft - You have to have fuel, and a furnace/brewing stand, to process things. These take time. You can use a campfire on a few things for convenience. More time, no fuel requirement. Only one 'person' can use these at a time. More accurate to say that each workstation has a throughput limit, people would need to make their own. The ability to make an infinite amount of their own should be ignored for the purposes of the question (that's back to EVE and SWTOR).
FFXI - You have to have crystals, one per craft, to process things. These take a little time to do the task, but time to gather. Throughput of crystals in the world overall limits the amount of crafting in the world that can happen moreso than the time to craft does, but for big bulk work, the time limitation starts to matter a bit.
BDO - For the few things that require you to have a workstation with durability (Alchemy, Cooking), the Time is the important thing. Optimization is all about bringing down the time, for bulk work, and non-bulk stuff is limited by materials, not 'fuel/Durability'. Everyone can buy or make those stations infinitely and put them in their houses, though, and... I'm skipping the rest of the detail, it's relatively terrible and not terribly relative (to the point).
BDO ('Animal Husbandry') - Your own stable slots are 'limited', but P2W + 'the actual part of the process being per player' means that there's no overall server throughput limit.
Optimized MineCraft (but no hax, cheats, dupes, or Create mod except maybe the carpet duping thing) - Space is the limiter here. You have to build the factory yourself out of components that you have to collect, but once you've done it, sky's the limit. For the 'farms' that you can use to generate the input items, same thing. For various reasons I'm counting the carpet dupe like this, familiar players probably know why. Infinite fuel is not hard ENOUGH to achieve through just 'factory' that it needs to be considered an exploit in itself, it's just less initial time to reach the same balance point.
With all that out of the way:
If everyone can use the Processing station or Stable to do their stuff at the same time, and never affect anyone else, we get the BDO throughput, unless the materials/fuel input required are tuned to the FFXI level (I'll take it! But it's hard, and hardcore, I'm told).
If they can't, someone or something must decide who gets to use it next. A scheduler, a person, or the good old fashioned 'hundred players/bots in an area clicking on an NPC' approach.
A StableMaster would be able to set, for EXAMPLE, priority. In fact, hopefully just Priority, but I'm learning not to expect this as a given for design in Ashes.
With a reasonable timing/number of slots, being able to go through and set Priority on the 'Processing Stations/Breeding Pens' for specific people, guilds, whatever, should probably not result in a lockdown if they can't outright prevent anyone else from doing it. Maybe limit to Citizens only. Maybe a default priority to players with higher craft skill. This part doesn't matter to me. Two things matter to me:
1. I don't know if this (the limitation on number of people who can use stations) would be a problem for people to the point where Intrepid would be pressured to go to the BDO method.
2. The Mayor doesn't have time for this, but it's part of Node Management (I don't care what is done about this, I'm just wondering what people think of it)
Bonus: If you don't mind the limitation, but
don't hate the idea that anything other than Might Makes Right matters (you can just have a mage alt to AoE down everyone around the NPC every time you want to cut the line, right? If you don't need to do it too often, it's fine, it's part of leveling your craft quickly, point is that we don't have to worry about crowds of clickers in Ashes of Creation because we can solve our problems with Indiscriminate Violence(TM)):
What would you want to determine who can use the Processing Stations when multiple people want to use them?
Opinions plz. The data, I must have it...
