Durability Question...

Do different items lose durability faster than others? For example, I duel with my Fury Seraph on my Zeal Pally all the time, but I only lost like 10 durability in a shit load of duels, I don't really remember how many though. And yesterday, I got an Ethereal BStar with 87 Durability on it, and after 2 duels, it was at 85 already....

Do Ethereals lose durability faster than normal, or runeworded, etc. weapons?

The BStar duels were not long either, they were much much quicker than some of the hacking on Barbs and Druids with a lot more life I was doing with the Fury...

Any ideas?

its based on number of hits, no type of items lose durability faster or slower, Besides Javalins (throwing weapons) (they lose their durability at 1/3rd the rate of other items (they have lower durability anyways)
