Considering all the "improvement ideas" I read as major additional annoyances in combat (ehm, that's not how improvement works guys)... I also heavily vote for "kill it with fire".
I don't see anything worthwhile coming out of durability without a LOT of testing, tweaking and trying. Taking massive amounts of time. And generally risking an extremely high probability of still reaching the "it's better left out of the game" conclusion anyway.
