It could be, but the logic doesn't support an increase. Taking a look at similar changes in the past supports the outcome of it being reduced rather than increased. Confectioner, alchemist, scholar, and tinker schools have had changes made to them in the past, all of which should have supported and helped Istaria see an increase in player interactions and economy. Although they were all great changes and content additions, a boost to the economy in game is something that never happened and the economy is still broken.
Past threads on the subject of a working economy in game are all over these forums and have lead to the same answer. There is no way to fix the economy of the game and how it works (or doesn't) unless the crafting and vendor systems are completely rewritten or redesigned.
Moving on to address and further expand on player to player interactions. Player to player interactions do not occur with consigners and vendors. With techniques added on at the time of item creation there is far more interaction that goes on then there would be with a system of mass produced tech-kits which would get stocked on a consigner/vendor for cheap, just as potions, dye-kits, scrolls, and confectioner items already are.
At present, if a player wants an item with techniques on it, then they must ask a crafter who has the techs they want to make it for them. The player must describe the weapon/armour/jewelry item that they want made and what techs they want on it to the crafter. The crafter will most likely let the player know what tech components are needed and how many, and the player will have to fetch those. Once the comps are gotten, the crafter then has to assemble the item for the player, so they have to meet with each other. The item is then made and payment if required is exchanged along with the finished item. That is quite a fair amount of player to player interaction for an item that has techniques on it.
With a tech-kit the crafter would be able to mass produce them and place them on a consigner or vendor for sale. Tech-kits would be just another line of mass-stock consigned goods, handled in the way in which potions, dye-kits, scrolls, and confectioner goods already are in game. The only interaction made player to player would be for a player to ask and be told by the crafter (or another player) to go see the consigner or vendor, (or to aid the crafter in noting that their stock on the connie was low and would have to be replenished.)
All of the above when taken together shows that there is little to no chance for any increase in interaction, and if anything it shows that a decrease is the most likely outcome.
Don't know how I missed this, but I fully agree with it. I would rather see this.
