I thought Everquest 2 had the best crafting system I had ever used in an MMO.
For those unfamiliar you harvested nodes for materials and then you went to a crafting station that allowed you to create 4 levels of items. There were durability bars and progress bars, and things would happen randomly where you would need to use a "Crafting spell" to counter in order to make the best possible item. If you failed to counter the different problems you could get a lesser quality item then you were trying to make. Although they didn't make it to terribly hard to craft the item, if you wasn't careful you could fail.
So the system kept you entertained while you crafted it was like a mini game. it did get tedious but it least it kept you busy while you was creating something.
WOW for the second best and all around easiest. Strait forward not very time consuming, but when I played no real benefit to crafted items. This was before lichking which is when I stopped playing. So I don't know if it developed into anything else.
I did a little crafting in guildwars 2, eq1, vanguard, and a few others. Crafting is one of the reasons I play mmos, so I was very disappointed with swtor's system and even more so with the update.
