A positive thing though, that a dual-DK'ing friend of mine has discovered, is that turning into a ghoul upon death seems to make you take no durability loss.
That is, having that talent makes your repair costs for that character be solely what you lose during combat, and take no extra durability loss from dying.
This should also make it less painful to test ghoul abilities ad such for those who wanted to do that.

@Ualaa: As mentioned in a post earlier, instead of finding a mob so you can explode, you can right click the buff to suicide.
