I would love to see a new crafting table be added called the recycling table. Using this table you can destroy items in your inventory and in return gain crafting materials, and return any gem socketed in the item. This would allow a player to choose rather to keep the gear, or the gem. This table would also provide another method of farming for reagents.
on a side note as far as crafting goes, I would like to see amber available at a lower level then it currently is, that or the amber need for crafting spells removed. These are five pip spells that are more useful at a lower level but cannot obtain them until much later. Unless you farm loremaster all day, and that drop chance is way too low.
