Game Mechanics Single Use Craft-Without-Level-Restriction device for crafting professions

I have mentioned this device on the "random event" thread and I think it would be better to have a discussion on its own. What this device does is to allow players to use specific crafting stations to craft items with levels up to this device's level cap while ignoring the player's own crafting level, as if the player's crafting level is equivalent to the device's level. As such, it offers a window to professions for a lot more players.

Here are some rules of the device:

1. The device is single use, and is consumed after use.
2. The device should be rare to encounter and not purchasable with any merchants (quest rewards is fine), similar to the weapon/armor gained from killing mobs.
3. There will not be any device that does gathering, and players can get the materials from the player market. This will boost sales of lower level gathering materials.
4. The device with a level cap of lv90 or higher should not be obtainable to not ruin end-game profession leveling.
5. The device should be untradeable as the purpose is to encourage players to try out professions themselves instead of selling them and "leaving them to the professionals".
6. Development team can adjust or nullifies the XP gains when crafting with this device.

Some of the rules I just came up with and may not be agreeable to everyone. If that is the case, let me know in the comments.

 

Okay but why can’t the player just ask someone else to help them craft the item like people currently do all the time
