Each year, the number of crafting sets increases, which means 24 crafting stations should be placed in the guildhall. The biggest houses have only 700 slots, so a vital part of those slots will be used not for decoration but for crafting stations. We have quite ugly fields of those stations in guildhalls; this isn't cool. What do I recommend as a solution? A Mastercraft station. It will consist of 4 crafting stations and a "container" for special crystals that can be filled/attuned from overworld crafting stations, like this works for attunable crafting stations. The Mastercraft station will allow choosing and crafting any of the sets among the crystals in the "container". And this will require only 5 slots in the house, so any player can place the Mastercraft station and fill it with crystals with preferred sets. Crystals can be sold by the same vendors/places as attunable crafting stations, but they can cost 4 times more, as they will represent the ability to craft the set in multiple crafting stations at once.
