Durability in this game is good because the damage you do never changes, and you can do 2x damage with the final throw. I hate it when I have a weapon that is basically useless because I've used it too much, and then I have to use a whetstone or go somewhere to fix it. This lets me focus on the world itself and find other weapons. It's also allowed me to try every weapon I've found to figure out which ones to grab and which ones to ignore. It's a great system, and I usually hate durability... it's one of the things I had to mod in TW3, along with encumbrance, to make it tolerable.
