Anyone else excited about this? This to me represents a huge step forward, and looks like a solid mechanic for people to invest their time and energy into the crafting portion. I wouldn't be surprised if weapon, armor, and clothing repair and enhancement became the primary reason for advancing skills. Gatherer type jobs would be useful for finding the repair items giving them a decent purpose, and the crafters would need to use these resources to initiate the repair/replacement.
Come to think of it, years back EQ had an Enchanter class. I'd love to see something similar in regards to equipment enhancement in game.
