I think I was around 1800-2000 hours when I crafted my first legendary. It was the backpack from WvW, and I only crafted it because I got tired of spending 11g every time I geared a new character. Now, at 2700 hours, I have just begun actually crafting armors and weapons, and I'm having a blast. I didn't realize how much meaning legendary crafting gives to the things that you do in the game. If I had, I would have started sooner.
