The present wiki page doesn't appear to directly address this - or maybe I'm not seeing it?

To clarify, in some games your weapons and gear begin to lose efficiency, when damaged/when their durability is lower. Do we know yet if this will be the case in AoC? Yours truly prefers a system where your efficiency is NOT impacted, until durability hits 0%. This is because it's quite discouraging to continue something like a big raid where the party has wiped 5 times, and with each successive attempt, your gear is less and less effective.
Or SHOULD it be the case that gear efficiency goes down with lower durability, in order to make death penalties more impactful?
