Why should there be any change at all?
I am a 100th level spellcrafter for example. Do I get any orders for crafting spells? Not even a single one for months!
Why is this the case when everyone around me constantly adds new adventuerer classes and constantly needs new spells? Why, when there're quite some new players starting a new career with Horizons?
Quite simple. They're in a guild an have their spellcrafters doing the work for free. And while crafting an item in the first place is quite feat to accomplish considering all the things you need, repairing them is just a simple thing.
You'll have the same problem and you'll change nothing about economy. The main problem being crafter-multiclassing.
Just try to imagine a scene in real life where all your friends and neighbours are highly specialized crafters in 1-10 professions and all have the required machines at their plots while resources are nearby. You can get absolutely everything you want and need right there in the street you're living crafted within a moment - and for free ... no economy will ever be possible then, even if your washing machine completely breaks down twice a day.
Another problem being players that completely undercut any prices at the market even with rare items that are in high demand, as is the case with forms and techs. The reason may be mass-farming or whatever. Prices drop steadily ...
The problem is the system itself, but since you cannot reverse the possibility of multi-classing and multi-classing is one of the main features of Horizins, the only fix to economy canbe achievedwith making proper useof exactly that system. Introduce items, that do not depend on single-player and/or single-profession crafting at all. Perhaps items so complex, that onlymulti-classed crafters with 2 to4veryspecificprofessions areable to make themand othersthat require several specialized crafters to work together for completition.
Crafting those items willbe a challenge even for multi-classed crafters and no doubt fun. And those items will be in high demand I suppose. Just make sure that especially forms for item creation thatrequireseveral crafters working together are introduced, since only then the whole community with their many beginners and remaining single-class crafters can benefit from such a system.
