Crafted Items Durability

I have a general idea of how durability works, but I don't really know how much durability is considered "good", or how much usage I can get out of a certain amount of durability. For example, how long can I last with just 150 durability?

If anyone with some experience in using crafted items can help it would be much appreciated,

 

I’ve found that ~150 durability will get you through most dungeons (unless you get multi hit 100 times). Normally just running around doing quests, as a HHIC player I’ve only needed to go back to repair my armour every 30 minutes to an hour. For a weapon though, they seem to last a lot longer as you don’t lose durability from just holding them like you do from wearing armour.

150 dura is considered good, and anything more than that is normally considered unnecessary imo.
